I was trying to load the windows driver in windows 10 using OSR Loader, the service for HelloWorld.sys has been created, but when I click on start, it's saying "This driver has been blocked from loading"

The video I followed: https://www.youtube.com/watch?v=Nc-uh8O989I

Upon investigating,

  • Driver compatibility issue → I tried set Target OS to Windows10 (Universal and then to Desktop)
  • Driver signature enforcement issue → ran bcdedit.exe /set nointegritychecks on
  • WDK might not be supported → Followed this video, https://www.youtube.com/watch?v=MjZVkuKQzTk&t=141s
  • Signing issue → ran bcdedit /set testsigning on
  • Tried testing from sc.exe command → sc create HelloWorld binpath=/my/sys/file type=kernel && sc start HelloWorld

  • Also, I tried using `devcon install HelloWorld.inf root\HelloWorld`, it says `devcon.exe failed` – tbhaxor Apr 19 '20 at 10:14

The problem was,

Target PC: Windows 10 Home x64
Kernel Mode Driver Target: Windows 10 Desktop x86

NOTE: The kernel build architecture must match the target machine architecture.

I'm posting this in case someone runs into the same error, but from a different use case. I was trying to find out cpu information running sysinternals CoreInfo executable as admin from a command prompt:

coreinfo.exe -v command. //The 32 bit system command.

Coreinfo v3.6 - Dump information on system CPU and memory topology Copyright (C) 2008-2022 Mark Russinovich Sysinternals - www.sysinternals.com

Intel(R) Xeon(R) W-10855M CPU @ 2.80GHz Intel64 Family 6 Model 165 Stepping 2, GenuineIntel Microcode signature: 000000EC Error loading driver: This driver has been blocked from loading

I used the set pro command from the same command prompt to verify 64 bit:

C:\>set pro

PROCESSOR_ARCHITECTURE=AMD64 PROCESSOR_IDENTIFIER=Intel64 Family 6 Model 165 Stepping 2, GenuineIntel PROCESSOR_LEVEL=6 PROCESSOR_REVISION=a502 ProgramData=C:\ProgramData ProgramFiles=C:\Program Files ProgramFiles(x86)=C:\Program Files (x86) ProgramW6432=C:\Program Files PROMPT=$P$G

However, because I have a 64bit system, this was the correct command and output:

C:\> coreinfo64.exe -v

  •   Supports Intel extended page tables (SLAT) URG             

  •   Supports Intel unrestricted guest

I needed to find out if my CPU supported SLAT mentioned above so I could install Docker.
