Default Behavior

The Udfs service is a file system driver. In Windows 8 it is disabled and therefore it won't start under any conditions. If Udfs fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the udfs service hasn't been started.

Restore Default Startup Configuration for Udfs

1. Run the Command Prompt as an administrator.

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

sc stop udfs
sc config udfs start= disabled

The udfs service is using the udfs.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is corrupted or deleted, you can put it back in there.
