Hello. I have a problem with my driver on some systems not being loaded on boot (SERVICE_BOOT_START start type), while it can be loaded perfectly fine after the system has booted. The fact it only happens on some of my customers systems really makes me wondering.
The only error message I see in the Event Log is event code 7026 from Service Control Manager:
The following boot-start or system-start driver(s) failed to load: drivername
The driver is signed via Attestation signing @ Microsoft dev portal. It only imports functions from ntoskrnl.
Is there any way to get more info on this problem? I have searched msdn and could not find any suitable information on this event code.
