Default Behavior

FileCrypt is a file system driver. In Windows 10 it is starting at Kernel initialization. If FileCrypt fails to load or initialize, Windows 10 attempts to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration cannot be applied or working improperly, Windows 10 startup process halts with a Stop error. If you disable or delete the FileCrypt service, Windows 10 won't start.


FileCrypt cannot be started under any conditions, if the FltMgr service is disabled.

Restore Default Startup Configuration for FileCrypt

1. Select your Windows 10 edition and release, and then click Download.

2. Save the Win10_FileCrypt_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The FileCrypt service is using the filecrypt.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 10 installation media.
