WHAT IT IS
AND WHAT YOU CAN DO

Mad

MAD.exe

(Microsoft)

Windows NT4/2000/XP Server editions only.  This service is the System Attendant Service for Microsoft Exchange Server from version 4.0 onward.  MAD is a necessary background service for Microsoft Exchange Server – some of its many functions :  to load the required DLLs whenever you configure Microsoft Exchange, to periodically check if users have been added to the Site and Configuration containers, to write log messages to the Message Tracking Log File on behalf of MTA (Message Transfer Agent) and the Internet Mail Service, to generate the offline address books.

Recommendation :
The System Attendant Service is a crucial service of Microsoft Exchange Server.  If you experience 100% CPU utilization problems, duplicate log entries, MAD instability, or other problems which you can track back to MAD, then ensure you have the latest Service Packs for both NT4/2000/XP Server and for the version of Microsoft Exchange Server which you are running as every Exchange Server Service Pack has one or more fixes for this crucial service.

Magickbd MagicKBD.exe

(Samsung)
MagicKeyboard Utility found on Samsung laptops, and some Gateway laptops, which enables the user to program keyboard keys to start specific applications, such as your Internet Browser, your Accounts Package, your E-mail software, etc....  The reprogramming of keys is done via the MagicKeyboard icon in the Control Panel.

Recommendation :
No known problems with this background task – we suggest therefore to leave it running.
Mapisp32 MAPISp32.exe

(Microsoft)
Microsoft Windows Messaging Subsystem Spooling Application, often referred to as the MAPI Spooler (Mail Application Programming Interface).  The MAPI spooler sends the messages that are waiting for despatch in your Microsoft Exchange, Windows Messaging, or Outlook 97/98/2000 outbox.

Recommendation :
MAPISP32 is an essential component of Microsoft Exchange, Windows Messaging, or Outlook 97, 98 or 2000 (we are investigating Outlook 2002).  MAPISP32 will sometimes get stuck and there are many causes and solutions to the problem.  Contact us if you have problems with MAPISP32.
Mathchk Mathchk.exe

(Real Networks)
Another RealOne Player background task.  See RNDAL and EVNTSVC elsewhere in these pages for more details about RealOne Player. We do not at this stage know what purpose MATHCHK serves.

Recommendation :
We do know, however, that renaming MATHCHK.EXE to MATHCHK.OLD has no adverse effect on the running of RealOne Player (that is, of course, if you decide not to uninstall RealOne Player).
Mbm5 MBM5.exe

(LiveWireDev.com)
Motherboard Monitor 5 System Tray icon.  It enables you to access the various Motherboard Monitor temperature and system fan readings, and configuration settings, via the System Tray.

Recommendation :
The System Tray is the best place for this particular program.
Mcagent McAgent.exe

(McAfee)
McAfee Agent. Task installed on network versions of McAfee AntiVirus.  This task communicates with the central fileserver and ensures that the end-user PC has the latest McAfee antivirus software and updates which the fileserver has to offer – it downloads the updates if necessary.

Recommendation :
Refer to your network administrator.  We do not have any knowledge of problems with this task.
Mcshield McShield.exe

(McAfee – Network Associates)
McAfee On-Access Scanner for Windows NT4/2000, present in McAfee VirusScan 4.x, McAfee NetShield 4.x, and in the Business Management McAfee Protection Suite for networks.  This task virus scans files in the background as and when you access them.

Recommendation :
Essential for the proper protection of your PC against viruses – leave alone.
Mcupdate McUpdate.exe

(McAfee – Network Associates)
AutoUpdate & AutoUpgrade background utility task which comes with McAfee VirusScan 4.x.  Its purpose is to automatically update your McAfee software with the latest virus updates and software updates whenever you connect to the Internet.

Recommendation :
Disable the AutoUpdate feature within McAfee VirusScan and make a point of regularly updating VirusScan manually.  In our opinion there are too many problems with MCUPDATE to bother with it.
Mcvsescn MCVSEscn.exe

(McAfee)
McAfee VirusScan Email Scan Module.  Task which has appeared with the latest updates to version 7 of McAfee VirusScan (late August 2003).

Recommendation :
Oh Dear Oh Dear Oh Dear !  In its initial incarnation in late August 2003 / early-mid September 2003, this process has been a nightmarish task and in our opinion this is totally inexcusable.  AntiVirus software is an absolute necessity – it is not a choice, it is a necessity these days.  Thus the last thing you want is your antivirus software to behave ...... like a virus (!!), which is exactly what this task has done in its original incarnation, and at the time of writing, 29-Sep-2003, it is still causing havoc to many AnswersThatWork users.  From the creation of huge never-erased temporary files (TMP files), gobbling up the user’s entire disk space in some cases, constant hard disk access, high CPU utilization resulting in other tasks "not responding", to the inability to send or receive emails, this task has shown, in our view, what software at its worst can do.  Shocking, shocking, shocking.  If you are experiencing any of the above problems, download the latest updates from McAfee as they will probably have fixed the problem by the time you read this.  If, even after updates, you still experience problems, disable ScriptStopper and WormStopper within McAfee and then disable or delete this task with Starter.
Mcvsrte MCVSRTE.exe

(McAfee)
McAfee automatic updates background task for some of the older versions of McAfee VirusScan and for McAfee’s VirusScan Online products.

Recommendation :
Not sure. We have not had any reports about this task, nor have we come up against it often enough to know.  We recommend therefore that you leave it alone.
Mcvsshld McVSShld.exe

(McAfee)
McAfee ActiveShield. Background task which is part of McAfee VirusScan Online and which virus scans files in the background as and when they are accessed.

Recommendation :
An essential part of McAfee VirusScan Online – leave alone.
Mdm MDM.exe

(Microsoft)
Machine Debug Manager. Windows 98/ME/2000/XP.  This is used purely by Technically Advanced Users and Developers, and in very specific cases at that.  It is not needed in most normal day-to-day uses of a PC.

Recommendation :
There is a bug with MDM where it will regularly create zero-length temporary files in the Windows folder and not delete them.  If you do not do regular housekeeping you can end up with hundreds of such files.  Disable, or best, delete using Startup Manager.  Note, MDM has a way of restarting of its own when Windows encounters certain conditions – to prevent it from starting altogether many advanced users, ourselves included, resort to renaming MDM.EXE to MDM.EXE.OLD; that solves the problem permanently.

Mdmsetpe

MDMSetPe.exe

(Aztech)

System Tray configuration icon for Aztech modems.  The icon enables you to set up the country for the modem, and the modem audio mode.  Through an oversight the modem drivers installation utility installs this configuration icon in the System Tray but does not install an alternative way of starting it up in the Aztech program group that it creates.

Recommendation : 
Harmless. Once you have configured your modem you can choose to keep the icon in the System Tray, or you can choose to disable it with Startup Manager.

Mediadet Mediadet.exe

(Creative Labs)
Creative Labs Disc Detector background application which gets installed with some Creative Labs sound card drivers.  Disc Detector detects when you insert a CD in your CD-ROM drive and then automatically starts the appropriate application for it.  You can determine whether it should open in Creative PlayCenter, or some other audio player.

Recommendation :
Windows does this very well already.  It beggars belief that Creative Labs should have thought it a great idea to clutter the System Tray with an application that duplicates what Windows already does well.  As with Creative’s CTNOTIFY, we recommend you disable MEDIADET. To do so, open the "Disc Detector" icon in the Control Panel and uncheck "Enable Disc Detector" in the General tab.
Mgabg Mgabg.exe

(Matrox)
Matrox BIOS Guard task.

Recommendation :
We have no idea as to what this task does.  However, from the name, it is unlikely that disabling it will impact the operation of your Matrox graphics card, so you could experiment with disabling it with Startup Manager.

Mhotkey

MHOTKEY

(??)

This utility seems to get installed with the software that comes with the type of keyboards called "Internet keyboards",  and in most cases is associated with an icon in the System Tray.  It would seem that its purpose is to enable the end-user to program certain key combinations or function keys to do specific tasks,  or access specific sites,  while browsing the Internet.  We do not know much more than that,  except that in many instances a bug in the software prevents the use of the keyboard in DOS session windows !!

Recommendation : 
Either uninstall the keyboard software which installed this program (via the "Add/Remove Programs" icon in the Control Panel),  or disable it with Startup Manager.  It is better to use the Netscape Bookmarks or Toolbar Buttons feature,  or Internet Explorer’s Favorites,  than expose yourself to a program which seems quite buggy.

Minilog

Minilog.exe

(Zone Labs)

Alert logger task for the Zone Alarm Internet firewall. This task creates and updates the log of intruder attacks.  This task is only started if you select the "Log alerts to text file" option in Zone Alarm.

Recommendation : 
Deselect "Log alerts to text file" in Zone Alarm if you do not want this task and you have no special need for intruder alerts to be logged.  Do not under any event manage this background task using either Startup Manager or MSConfig, as it can result in interminably slow Internet access if you have "Log alerts to text file" selected but you have at the same time prevented this task from starting using either Startup Manager or MSConfig.

Mixer

Mixer.exe

(C-Media Inc)

This replacement for the default Windows Volume Mixer gets installed when you install the drivers for C-Media onboard sound systems or sound cards.  In our opinion the C-Media mixer is no better than the default Windows mixer and, if anything, it is irritating in the way it will by default mute the CD-in, Line-In, and other volume settings on some PCs, making the end-user lose valuable time working out why the sound is not working.

Recommendation : 
Disable or Delete using Startup Manager.

Mk9805 MK9805.exe

(Cherry??? / Chicony???)
See CHotKey.

Mm_tray

Mm_Tray.exe

(MusicMatch)

This program is installed by MusicMatch Jukebox and enables you to access MusicMatch from the System Tray.

Recommendation :

If you like the feature, keep it.  Otherwise disable the Tray feature in MusicMatch Jukebox.

Mmc MMC.exe

(Microsoft)
Microsoft Management Console.  A massively irritating piece of software that you have no choice but to use to manage most of Microsoft’s latter system products (SQL Server, Exchange server, and more...).  At the time of writing, 23-Jan-2003, there is nothing we like about Microsoft’s Management Console.  First it’s slow.  Second, it’s slow.  Third, it’s slow.  You can’t have it open in Maximised mode, you always have to maximise it manually.  It won’t remember your column widths.  It won’t remember your column rearrangements, it won’t remember your sort order, etc.., etc..  It is an incredible time waster, yet you are stuck with having to use it, and more often than you realise – when you are in any Administrative Tool in Windows 2000/XP, such as "Computer Management", that is what you are using and that is why it appears in your Task List.  Can you ever remember wasting soooo much time managing system stuff in Windows 95/98/ME ?  Of course not.  Who wrote this MMC rubbish ??!!

Recommendation :
As explained above, it is an integral part of Windows 2000/XP and opens up when you are using any Administrative Tool, that is why it shows in the Task List. However sometimes, because of bugs, it remains in the Task List even though you have no management window open anywhere.  When it does it consumes memory (but not CPU time) – you can End Task on it.
Mmkeybd MMKeybd.exe

(Netropa)
One-Touch Multimedia Keyboard handler task which enables you to use the pre-configured or user-configured one-touch keys, such as the "Internet" key, the "Email" key, etc.  An icon is displayed in the System Tray which enables you to configure your one-touch keys.  This Netropa software is used by many PC manufacturers and is called differently by each of those manufacturers :  Packard-Bell calls it ActivBoard, it is Easy Access on some Compaq PCs, Keyboard Manager on some DELL PCs, Keyboard Manager or One-Touch Multimedia Keyboard on HP PCs, etc...

Recommendation :
MMKEYBD is essential to the proper functioning of your multimedia keyboard – without it one-touch keys and, occasionally, sound, will not work.  Problem :  for some reason which we feel can not possibly be justified, this task tries to communicate with specific servers out on the Internet !!  We have no idea as to what it sends out or receives, but we know it cannot possibly be justified – this is just keyboard software after all.  So, if this aspect of the software worries you, either get a firewall and block MMKEYBD from communicating with the Internet, or disable MMKEYBD with Starter knowing you won’t be able to use your one-touch keys.
Mmod MMod.exe

(EZula)
You have EZula software on your PC

Read EZULAMAIN for more details.
Mmtask MMTask.tsk

(Microsoft)
Microsoft’s Multimedia Background Task Support Module.  This is a hidden task in Windows 9x/ME which shows up only in the Processes List in Starter.  MMTASK is a Microsoft background task which provides simulated multitasking for multimedia applications, so that, for example, you could be playing more than one AVI movie at the same time.  This task does not exist in Windows NT4/2000/XP which are true multitasking operating systems.

Recommendation :
Leave it alone. If you experience error messages which mention MMTASK, and quite a few users do, then the problem is in most cases elsewhere, very often driver problems.
Mmtray MMTray.exe

(Morgan Multimedia)
System Tray icon which enables you to call up the configuration utility for the Morgan Multimedia MJPEG Codec.

Recommendation :
Unless you work a lot with MJPEG AVIs and need to change the Codec’s configuration often, we recommend disabling this with Startup Manager (to reduce System Tray clutter) and accessing the configuration screen via the "Control Panel \ Multimedia" icon.
Mmusbkb2 MMUSBKB2.exe

(Netropa)
One-Touch Multimedia USB Keyboard handler task.  Same as MMKEYBD above but for USB multimedia keyboards.

Mobsync

MobSync.exe

(Microsoft)

Microsoft Synchronization Manager.  This program, which is part of Internet Explorer 5.x/6, runs in the background when you are using the "View pages offline" feature of Internet Explorer, and you have set parameters for when your pages should be automatically synchronised, or you decide to manually synchronise your offline content with the web through the "Start \ Programs \ Accessories \ Synchronize" function.  This program will also run if you are doing development using Microsoft SQL 7 and using SQL 7 replication.

Recommendation : 
Harmless. If you never use the "Synchronize" function, then disable it with Startup Manager.

Monwow

Monwow.exe

(Symantec)

Part of Norton CleanSweep. This program monitors the installation of new software on your PC – without it running in the background Smart Sweep is "toothless" and cannot be used.

Recommendation : 
If you actively use Norton CleanSweep on your PC, you will need to leave this process alone.  Only disable it if you are troubleshooting conflicts between CleanSweep and other software (disable it by turning "off" Smart Sweep in the configuration of CleanSweep, and then rebooting).

Mosearch MOSearch.exe

(Microsoft)
Microsoft Office XP Fast Search.  Well, well, remember the nightmarish Find Fast of previous versions of Microsoft Office ?  MO Search is the Office XP equivalent.

Recommendation :
New name, same problems.  Endless trashing of your hard disk when you are not using it, and sometimes when you are, with delays in mouse movements, or downright temporary inability to do anything for a few seconds (while MOSEARCH is updating its indexes).  The search speed gains are negligible and yet, as with Find Fast, the constant disk activity and response delays irritate end-users immensely.  Try disabling MOSEARCH with Startup Manager.  If that is not possible, then you will have to de-install "Support for fast searching" out of Microsoft Office XP, and then rename the program files MOSEARCH.EXE and MOSDMN.EXE by adding .old at the end of their names.
Mostat MoStat.exe

(Wurld Media Inc)
Part of the Wurld Media advertising network software which comes in the shape of an Internet Explorer browser helper.  In addition to gathering information and statistics about your browsing habits, and transmitting them back to Wurld Media, at the time of writing, January 2003, whenever the end-user tries to go to specific well known sites, the software first takes the end-user to a site that is part of the advertising network, and then redirects the end-user back to his original target.  In most cases the end-user does not realise this has happened unless he watches the URLs being accessed in the Internet Explorer status bar.  Although we have our own ideas (call them assumptions), we are not quite sure as to the purpose of this behaviour.  Wurld Media advertising software is most often installed with the Morpheus file sharing program.

Recommendation :
We won’t have this software on any PC we own or support.  If you want to follow our lead download SpyBot Search & Destroy from our Downloads page and use it to remove Wurld Media advertising software – be aware, however, that this may disable whichever program installed it, Morpheus for example. Note that de-installing the "carrier" program will in most cases not de-install the Wurld Media software, you will still need SpyBot to completely rid your PC of it.
MotiveMonitor

Motmon

Motmon.exe

(Motive Communications – Motive.com)
Part of DELL’s Resolution Assistant which ships with most DELL PCs.  MOTMON is however also found on Compaq and HP PCs. Wherever it is found, it is in fact bought/licensed from Motive Communications and is software which purports to enable your PC supplier to better support you. DELL’s description of MOTMON :  "The Resolution Assistant provides an easy-to-use graphical interface for submitting service requests and keeping track of service requests you have already submitted".  The Resolution Assistant enables you to submit problems via the Internet, with information collected by the Resolution Assistant also submitted automatically in the process (Resolution Assistant does give you the ability to control what is sent, although you will never know if it sends information other than what it gives you control over).

Recommendation :
If you have a DELL PC, and you are still within the support period with DELL, you may wish to leave it alone. Many users, however, have complained of "unknown errors" with MOTMON.  Since this software is definitely not essential to the good running of your PC, if you experience such errors, or you are worried about your privacy, simply disable MOTMON with Startup Manager.
Mpfagent MPFAgent.exe

(McAfee)
McAfee Personal Firewall Agent.  This background task is responsible for implementing the security services and rules of your McAfee Personal Firewall product.

Recommendation :
Essential to the proper operation of McAfee Personal Firewall – leave alone.  Note, however, that MPFAGENT has a tendency to misbehave and run away with CPU resources on some PCs after the installation of Windows 2000/XP Service Packs, so it is a good idea to re-install your McAfee Personal Firewall after the installation of an MS Service Pack and/or update it online with the latest updates.
Mpftray MPFTray.exe

(McAfee)
McAfee Personal Firewall Tray icon.  This icon, showing as a big M, enables you to access all the features of McAfee Personal Firewall from the System Tray.  You can view reports, check the details of specific alerts, and also access all the other features of the product.

Recommendation :
Our advice, for all firewall products, is to leave the System Tray icon running, as firewall protection is crucial and these tray icons typically change their visual appearance to notify you of a particular event that you should investigate further.
Mprexe MPREXE.exe

(Microsoft)
This is the Windows Multiple Provider Router. This program allows Windows 9x/ME to have more than one network client, protocol, or adapter – its function is to route network requests between the different adapters and clients.  On Novell NetWare networks, MPREXE will sometimes hang on boot-up or logon depending on the particular software mix on the PC concerned.  In our experience most MPREXE problems on a Novell network are resolved through both upgrading the network card drivers and moving to at the very least version 3.32 SP1 of the Novell Client for Win9x/ME.  The likelihood of the problem is also significantly reduced if you pare down your Network configuration to only those protocols that you will actually need, as per the recommendations of our Network Troubleshooting document in our "Hottest Tips" library.

Recommendation :
None – MPREXE runs transparently and will only appear in your Ctrl+Alt+Del Task List if there is a problem that has caused it to hang; it will not show otherwise and you will have to run a program like Starter to see it running transparently.  Therefore, if it shows in your Ctrl+Alt+Del list you know you have problems that you will need to resolve.
Mpservice MPService.exe

(Canon)
Canon MultiPass Service.  This service is installed by the Windows NT4/2000/XP drivers for Canon MultiPass multifunctional printers.

Recommendation :
Some versions of the drivers have a buggy MPSERVICE which either consumes excessive amounts of CPU (up to 100% even!) or which shuts down complaining of a "conflicting device" or "device in use".  If you experience such a problem download the latest drivers and that should cure the problem.  Note :  to either uninstall the MultiPass driver, or to upgrade it, you need to first stop the MPSERVICE service or you will not be able to uninstall or upgrade.

Mrtmngr

MRTMngr.exe

(Intuit)

Maintenance Release Task Manager for Intuit’s QuickBooks or Quicken.  Many of Intuit’s background downloading tasks can sometimes create serious conflicts, from illegal operations and invalid page faults which mention the MRTMNGR, MRTRATE, MRTPROC, or QAGENT programs, to the modem attempting to dial on boot-up, inability to print after going online, or the printer being activated when going online. For all these reasons we strongly recommend disabling all Intuit background downloading tasks.

Recommendation :
 
Disable from within Quicken/QuickBooks – choose the "Edit \ Options \ Internet Options" menu option.  Press Alt+Shift+4.  Click "Yes" on the window asking you if you want to disable the Quicken Background Download Manager.  Click OK.  Close Quicken.  Restart your PC.

Msbb MSBB.exe

(180Solutions.com)
Ad serving software which pulls up advertisements from ad servers whenever you are connected to the Internet.  MSBB is part of the n-CASE product from 180Solutions and gets installed by a variety of FREE downloaded products (many music file sharing programs) who make their money through the advertisements that you receive while browsing the Internet.  Here is the 180Solutions write-up on n-CASE as of 19-May-2003 – aimed at software writers :  "We own the largest and easiest to use Comparison Shopping Network ever created, now with over 16 million users.  The majority of our distribution comes by partnering with developers and providers of widely distributed, consumer-oriented software.  By partnering with software providers, and bundling our n-CASE software (just over 100k in size) with other downloadable software applications, we provide our Distribution Partners with a critical revenue stream.  When bundled with other software products, we don't charge the user for our software - and instead offer it to the consumer for free to install if they desire (a $4.99 value).  Once installed, we provide the user with contextually based shopping alternatives which then generate money for us based on our partnerships with the comparison shopping sources.  We can then either share with you a percentage of the revenue generated from your users, or pay you a flat fee per install, whichever you prefer".

Recommendation :
There is nothing good we can say about MSBB.  Internet browsers slowing down to a crawl is the most common complaint, but we have also seen random "MSBB has encountered an error and will close", or MSBB trying to start the dial-up connection for those connecting to the Internet via modem, not to mention the extremely irritating random pop-up ads.  We suggest you remove MSBB by using Spybot from our Downloads library.  And we are not the only ones to suggest this – because of the name of the program (which suggests a Microsoft system program), and the frequency of problems with MSBB it, it is our guess that Microsoft received so many complaints or error reports about MSBB that they were moved to produce Knowledgebase documents which recommend the removal of n-CASE :  see Knowledgebase articles Q317714, Q320162, Q299964.
Msblast Msblast.exe

(???)
You have the BLASTER virus (also called LOVSAN).
Msdtc

Msdtcw
MsDTC.exe

MsDTCw.exe

(Microsoft)
Microsoft Distributed Transaction Coordinator.  The Microsoft Distributed Transaction Coordinator is a transaction manager which permits client applications to include several different sources of data in one transaction and which then coordinates committing the distributed transaction across all the servers that are enlisted in the transaction.  MSDTC runs on all Windows platforms and is installed by applications which need to use it, such as the Microsoft’s Personal Web Server, or Microsoft SQL Server.

Recommendation :
If you have it running, it is most probably needed by a Microsoft Application, so leave it untouched unless it is definitely causing you problems.

Msg32

Msg32.exe

(Nemesys Music)

Background task installed by the GigaStudio and GigaSampler music sampling software packages.  This task only shows up when you start using either package.

Recommendation : 
Necessary for the proper operation of GigaStudio/GigaSampler.

Msgloop

MsgLoop.exe

(Crystal)

Background program which gets installed with the drivers for older sound cards based on the Crystal chipset (eg. Adlib Audio, Aztech, Acer). Description :  A WaveStream component which is provided to hook up with the Brooktree WaveStream CD, also called the "Brooktree WaveStream Message Server".  This background program is also present in the drivers for more modern sound cards but in this case MSGLOOP.EXE is called the "Conexant WaveStream Message Server".  These sound cards are often found in Hewlett-Packard PCs and some Compaq PCs.

Recommendation : 
There are reports of MSGLOOP preventing Scandisk and Defrag from working properly, or causing crashes at boot-up.  Since we are not certain about what MSGLOOP actually does, we recommend you leave it alone unless you experience strange problems, or you have changed your sound card, in which case disable or delete it with Startup Manager, and then test thoroughly.

Msgsrv32

Msgsrv32.exe

(Microsoft)

The Windows 32-bit Message Server.  This essential program normally never appears in the Task List unless it has "hung";  it otherwise runs invisibly in the background performing a variety of essential services, a significant majority of which being to do with on-screen messages and notifications.

Recommendation : 
As mentioned above this program only ever appears in the Task List if it has "hung".  When that happens you will see "Not responding" next to it.  Simply highlight it, and do an End Task on it (you may need to wait 5-10 seconds after the first "End Task" and re-do it).  If MSGSRV32 hangs often, you will need to investigate.

Msgsys Msgsys.exe

(Intel???)
We are not sure but we believe this task to be part of Intel’s LANDesk Management Suite, either licensed directly from Intel, or as part of a Symantec Norton AntiVirus Corporate Edition solution.  More specifically we believe this task to be part of Intel’s Alert Management System (AMS), itself part of the LANDesk Management Suite.

Recommendation :
None, as we do not yet know the role of this task.
Mshta MSHTA.exe

(Microsoft)
Microsoft HTML Application Host. MSHTA is the process that runs .HTA files (HTML Applications = programs written in HTML) under Windows.  Typically MSHTA loads as soon as a .HTA application needs to run, and then terminates when the application completes.

Recommendation :
Essential – leave alone.  Note, however, that if there are bugs in the .HTA files it was running, MSHTA will sometimes not terminate when the .HTA application has already completed, and will consume significant amounts of resources.  When this happens, doing an End Task on MSHTA solves the problem (only do so if you are absolutely certain that nothing else that needs MSHTA is running).
Msiexec MSIExec.exe

(Microsoft)
Microsoft’s Windows Installer program which handles .MSI product installation files.  This program does not normally run in the background if it is not in use.  However, many Windows 2000/XP users have reported seeing MSIEXEC in their Task List although we ourselves have never experienced this unless we were actually in the process of installing a product released in .MSI format.

Recommendation :
Leave alone if it is running (there probably is a valid reason for it to be running).

Msimn

Msimn.exe

(Microsoft)

This is the Microsoft Outlook Express 5/6 program.  Technically this is not a background task, and it should therefore not be listed on this page.  However, as we regularly receive reports of MSIMN showing up in the Task List even after Outlook Express has been closed down, we thought we would list it anyway.

Recommendation : 
If you end up with MSIMN showing up in the Task Bar even after you have closed Outlook Express (sometimes you may even have more than one instance), then the problem may be caused by the McAfee antivirus software.  If you do have McAfee, then go to the McAfee website to download all software updates (as opposed to virus updates) for your version of McAfee VirusScan.

Msmsgr MSMsgr.exe

(Microsoft)
Windows XP Messenger & the current version of MSN Messenger (effectively a newer incarnation of MSN Messenger below – MSMSGS).

Recommendation :
Down to end-user preference.  You can disable it in the same way as MSMSGS below.
Msmsgs Msmsgs.exe

(Microsoft)
MSN Messenger Service tray application.

Recommendation :
Disable or Delete with Startup Manager if you do not use the MSN Messenger Service. Alternatively, you can go into the "Tools \ Options \ Preferences" menu option within Messenger and uncheck "Run when Windows starts".
MsPMSPSv MsPMSPSv.exe

(Microsoft)
Microsoft’s WMDM PMSP Service, aka Windows Media Device Manager Pre-Message Security Protocol Service.  From our tests this service only appears in the Task List if you have done a Windows Update and updated Windows Media Player with the 26-Jun-2002 Security Update Q320920.  This services enables Windows Media Player to support the SDMI protocol (Secure Digital Music Initiative) when copying CDs or packaging copyrighted downloaded music to SDMI compliant music players and storage devices.

Recommendation :
This process takes at least 1.2Mb of memory, yet at the time of writing, November 2002, most users do not use any of the SDMI features of Windows Media Player.  Therefore, if you are such a user, we advise that you disable this process with Startup Manager under Windows 9x/ME, or set this service to manual in Windows 2000/XP.  You can always re-enable it if you start needing to use some of the SDMI features of Windows Media Player.
Mstask MSTask.exe

(Microsoft)
The Windows Tasks Scheduler, also called the Scheduling Agent.  Made active by default when you install Windows 98/ME – it appears in the System Tray as a blue box with a red stopwatch in Windows 95/98 and shows up in the Task List.  In Windows ME it is a hidden task visible only through the Processes list in Starter and there is no icon for it in the System Tray.  There is also no icon in the System Tray in Windows NT4/2000/XP but you can see the task in Task Manager.

Recommendation :
If you do not have tasks that you want to run on a regular basis, or you simply want to de-activate the Task Scheduler, double-click on the icon in the System Tray and choose the "Advanced \ Stop Using Task Scheduler" menu option;  then close it and Task Scheduler will no longer start automatically with Windows.  If you wish to re-activate it, you will find it in "Start \ Programs \ Accessories \ System Tools" (open it and choose the "Start Using Task Scheduler" option).

Mswheel

MSWheel.exe

(Microsoft)

Background task which is part of Microsoft IntelliPoint/IntelliMouse software and which provides support for the wheel in Microsoft (and Logitech) Internet mice.  The IntelliPoint/IntelliMouse software was developed to provide support for Microsoft Internet mice in Windows 95 and Windows 98.  However, all features of the software were incorporated in Windows 98 Second Edition, and all subsequent versions of Windows (WinME/2000/XP).

Recommendation : 
The IntelliPoint/IntelliMouse software has a history of incompatibilities.  If you run Windows 98 SE, Windows ME, Windows 2000, or Windows XP, de-install the IntelliPoint/IntelliMouse software and let the operating system handle all the features of your mouse.  If you are still on Windows 95, or on the Windows 98 upgrade version, or on the original version of Windows 98, and you are experiencing problems which seem to be related to your mouse, then ensure you have the very latest version of the IntelliPoint/IntelliMouse software from the Microsoft Download Center.

Muamgr Muamgr.exe

(Impact Software)
System Tray access to the MicroAngelo 5.x icon utility software.

Recommendation :
This icon simply adds clutter to the System Tray, particularly since MicroAngelo is not the type of software you will want to use on a daily basis.  Disable with Startup Manager.
Mxtask MXTask.exe

(V Communications)
Background task which is part of the Mijenix Fix-it utilities.  Fix-it was later bought by Ontrack, and then later by VCOM (V Communications) in October 2002. VCOM have since released Fix-It Utilities v5 (Thank you to the user who pointed us to the correct VCOM!!).  MXTASK is part of the auto-update feature of Fix-It v4.  It checks for updates to the Fix-It product and for antivirus pattern file updates.

Recommendation :
This task is an essential part of Fix-It Utilities v4 since it keeps your PC’s virus protection up-to-date with the latest viruses.  Should you absolutely need to, you can disable auto-update (MXTASK) from running in the background under the Fix-It v4 settings.
