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 of FileCrypt

Before you begin doing this, make sure that all the services on which FileCrypt depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

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

sc config FileCrypt start= system
sc start FileCrypt

3. Close the command window and restart the computer.

The FileCrypt service is using the filecrypt.sys file that is located in the C:\Windows\system32\drivers directory. If the file is removed or corrupted, read this article to restore its original version from Windows 10 installation media.
