File System Filter Manager Driver.
|Windows 7 edition||without SP||SP1|
The FltMgr service is a file system driver. If the FltMgr fails to load or initialize, the error is logged and the computer attempts to restart with the LastKnownGood configuration. If the LastKnownGood configuration fails, Windows 7 startup also fails, and the boot process halts with a Stop error. If you disable this service, Windows 7 will fail to start. Do NOT change this service startup configuration if your computer is working.
If the FltMgr is stopped, the following services will not start and initialize:
1. Select your Windows 7 edition and Service Pack, and then click on the Download button below.
2. Save the RestoreFltMgrWindows7.bat file to any folder on your hard drive.
3. Right-click the downloaded batch file and select Run as administrator.
4. Restart the computer to save changes.
Note. Make sure that the
fltmgr.sys file exists in the
%WinDir%\system32\drivers folder. If this file is missing you can try to restore it from your Windows 7 installation media.
