Please don't run this until you are asked to as it can put you in a boot loop



what is Driver verifier?

It is a part of Windows designed to reveal bad drivers. It tests them individually. It will cause Blue Screen Errors as that is its job

Driver Verifier monitors Windows kernel-mode drivers and graphics drivers to detect illegal function calls or actions that might corrupt the system. Driver Verifier can subject the Windows drivers to a variety of stresses and tests to find improper behavior.
When to run it?

Its running auto in background all the time but the only time you yourself need to run it is to identify drivers that are causing BSOD but hiding their actions behind windows processes. Often BSOD blame NTOSKRNL which is the Windows kernel. It was what crashed but not the actual cause. Running verifier can reveal the true cause.

The down side is it can leave you in a Boot loop so I generally suggest 3 steps:

1) Create a restore point

  • type "restore" then open "create a restore point"
  • create a new Restore Point now for C-drive
2) Create a bootable USB of Win 10 installer to use as a boot drive. download the Windows 10 media creation tool and use it to make a win 10 installer on USB

3) Set PC up to allow you to boot into safe mode

Open command Prompt (Admin)

Type the following:

Enter these BOLD commands and press ENTER after each.
(Note the colon after C with no space; then the spaces which are important - one after T before / & T before { & } before B & Y before L)
C:
BCDEDIT /SET {DEFAULT} BOOTMENUPOLICY LEGACY
EXIT


Now if you need to go into safe mode from boot, you "immediately" start tapping F8 (That means power button - then F8).

The 3 steps are just precautions. Once you have an installer and a restore point, and can get into safe mode from boot, you are ready to run it

NOTE: Even with the added steps, this can still break windows, so I can't guarantee the steps above are enough to fix the boot loops. Sometimes a clean install is only fix. I wish Microsoft could write a tool that didn't sometimes break their own software.

read the instructions carefully


Once it causes a Blue Screen of Death, upload the minidump file to your post, and we see what it shows us.

what to do if you get a boot loop

boot from installer
on screen after languages, choose to repair this pc, not install.
choose troubleshoot
choose advanced
choose system restore and roll system back to restore point created in step 1. PC should boot normally.



Alternate is use safe mode and enter a command they show you in the Microsoft link.



To disable safe mode at boot, go into command prompt (admin)

Type

C:

BCDEDIT /SET {DEFAULT} BOOTMENUPOLICY STANDARD
