File: wdfmgr.exe

Installation of Microsoft Windows Media Player 10 causes this module to appear in the Windows Task Manager. It is installed with a Startup Type of "Automatic." It is a convenience for owners of hardware MP3 players such as Apple iPods who want to synchronize their device content with Windows Media Player 10. The module's startup type can be changed to "Disabled" or "Manual" by users not owning a hardware MP3 player or not desiring synchronization. If the user later desires the service it can be changed back to "Automatic" startup. Instructions for changing the startup type are available from Support.microsoft.com. If you want a detailed security rating about your wdfmgr.exe (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager. www.neuber.com/taskmanager/process/wdfmgr.exe.html 

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!

This service causes your system to boot slower and needs to be disabled until the new WDF drivers are fully forced on us to have to use it. Zeus
It's part of Media Player 10; Under Windows Services it calls itself "Windows User Mode Driver Framework" and is set to load automatically at startup. If you don't want it to, change it from "Automatic" to "Manual" SMyTH

It's part of WMP10 and shouldn't cause a problem, but if it does, it can be stopped in process and set to manual start in services. Quite a common filename for viruses to use, so check that it's an official MS file in c:\windows or c:\windows\system32 Dr. Confused

wdfmgr.exe is not a virus, is a "personal" driver for Media Player 10 and meny new video & audio players.It is known as a Local Service, meaning that it use your internet connection to send/recive info. about media from ur playlist.I don't know why it have to do this, and what is helping for (us/creator), but u can remove it from C:\windows\System32\ (wdfmgr.exe) is there. Shift+Del it! Tnx for ur attention. AbadBoy
part of WMP10 - leave it alone. Osarika
This file is a considerably harmful virus, although it claims that it's part of Windows Media Player 10. It causes your playlist and songs to be relayed back to server. If you find this in your Task Manager (and especially if you find it in your task manager and WMP10 isn't installed or running) end it immediately, and do a search for it with hidden folders and files unhidden. Wherever you find it as an .exe, you're recommended to delete it for the safety of your computer. nyiddle

This is DEF. from Media PLayer 10 and or SP2. Uses 3 threads. It's suppposed to be for driver management (any poorly writen drivers will be detected and auto rollback will be initiated. However it does phone home and reports you media player database every now and again. For those of you with high CPU usage. START RUN type..SERVICES.MSC...right click (Windows User Mode Driver Framework) and stop it and also set to disable. Yur good to go.. WarRanger
Helps with installed plugins within Media Player 10. Leave it on manual in the windows services. If any plugins need it, it will turn on. If you disable the service, conflicts may occur when using Nero , other plugins and maybe, certain codecs. JackBlack440
If your going to play any games turn it off before you do, It will halt them while your computer reads something off the hardrive for some reason. kill it Rude
It's a service belonging to Windows Media Player 10. Its purpose is to sync your mp3 player with your PC (like iTunes does for iPod). If you don't have an Mp3-Player that you like to synch using Windows Media Player, you can disable it from the Services manager. see the MS link.  See also: Link Maarten Jansonius

it's not a Virus, but may not necessary. It's a Service, wich can be easily stopped unter mmc - "Services".

Since this, I decided to disable this "Service". DanDare

It can be 2 things. Another one is the windows media player 10 what sends played items back to momma. Another choice is Windows User Mode Driver Framework, if you need it it should not be disabled. I have the second one. If its the first one disable it. Tuomas

wdfmgr.exe, used by wmp10 to automatically link devices that share .wmv files such as Portable Media Devices. Without this file your devices will not communicate nor sychronize files. User Mode Man
The Windows User Mode Driver Framework service is a driver component that is used by Windows Media Player 10. The Windows User Mode Driver Framework service supports synchronization of content with hardware players. For example, an MP3 device is a hardware player. If you do not have a hardware player, you can set the Windows User Mode Driver Framework service Startup type setting either to Disabled or to Manual.  See also: Link writemars

This service gets installed on Windows XP when you either install Windows Media Player 10, or when you upgrade to Service Pack 2 for Windows XP. The WDFMGR is a framework that enables developers to create drivers for network connected devices and some USB devices, where the drivers run in user mode rather than kernel mode but still behave as standard Plug-and-Play drivers. geminicricket
Integral part of XP (and Vista); Per ATW: This service introduced in 9/2004, is now an essential service which you should leave running as, in 2006, many manufacturers have now produced WDF drivers and WDFMGR will therefore be needed for those drivers. PainMan

If you see wdfmgr.exe on your process list, then it is a trojan.

The Windows User Mode Driver Framework service supports synchronization of content with hardware MP3 players. If you do not have a hardware MP3 player, you can set the Windows User Mode Driver Framework service Startup type setting either to Disabled or to Manual. Later, if you obtain a hardware player and if you want to synchronize it with Windows Media Player 10, you can enable the Windows User Mode Driver Framework service by changing the Startup type setting back to Automatic. http://support.microsoft.com/kb/892552  See also: Link LeandroTLZ

it caused problems - when i opened an IE window, it initially would give me an "Internet Explorer cannot display the webpage", but the page would appear when I hit refresh. quarantining this file stopped that problem.
I don't have MP10 but recently installed some DivX stuff and wdfmgr.exe showed up in TM. I've disabled it in my current profile. I've noticed that my zone alarm "True Vector" service has been shut down a couple of times recently, so I'll keep an eye on that to see if disbling wdfmgr.exe "cures" that. hi_carb

Wdfme.exe doesn't have anything to do with Windows or WMP 9, 10. WDFME.exe is a Western Digital exe that runs its Front Parlor part of Western Digital Smart Ware software. It comes preloaded when you buy an external drive or other drives from WD, usually above the 500 GB drives. I have found that this takes up alot of CPU cycles (anywhere from 10 - 18% of CPU cycles) in the startup phase and then settles in to use approx. 26 meg of Mem. I definitely uses the CPU in the beginning (startup takes 2 - 8 minutes) and I was trying find out if anybody else has had this problem. MartinD
after a suspect java applet (later found to be infected) launched WMP without my consent to play a url I noticed this process along with WLIDSVC.EXE and the WLIDSVCM.EXE hanging around in my taskmanager which is also suspect and it could be a rootkit so beware, Windows-related objects, processes and dll's are all liable to be hijacked, these to the community are known as rootkits. terminate the process if you dont trust it.
