Default Behavior

Stexstor is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it. If Stexstor fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the stexstor service has failed to start due to the error.

Restore Default Startup Configuration for Stexstor

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

2. Save the Win10_stexstor_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The stexstor service is using the stexstor.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.
