Default Behavior

FltMgr is a file system driver. In Windows XP it is starting before Kernel initialization. If the FltMgr fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the FltMgr service has failed to start.

Restore Default Startup Configuration for FltMgr

1. Run the Command Prompt.

2. Copy the commands below, paste them into the command window and press ENTER:

The FltMgr service is using the fltMgr.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is changed, damaged or deleted, you can restore its original version from Windows XP installation media.
