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.

The stexstor service is using the stexstor.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.
