Default Behavior

Disk Driver is a kernel device driver. In Windows 10 it is starting by the operating system Boot Loader as a part of the driver stack for the boot volume. If Disk Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the disk service has failed to start due to the error.

Restore Default Startup Configuration for Disk Driver

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

2. Save the Win10_disk_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The disk service is using the disk.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.
