I activated Driver Verifier and rebooted. Nothing special happened.
I also ran Malwarebytes antivirus, which found nothing.
Here is how it began and how the workaround I used.
I plugged an extra hard disk to erase it. Windows started to crash after this hard disk has been removed.
I got BSOD on boot, with error code 0xc000007b and a file name.
After several attempts, I finally installed a fresh Windows on a extra partition that was available. From there I tried to copy the file from the fresh system to the broken one and reboot. If the same file was still mentioned, I renamed it to .old and rebooted. Another file was bad and I continued the same way until Windows started to boot.
Then I had the mouse but no keyboard. By using the on screen keyboard, I reinstalled the keyboard software (its a wireless Laser 6000 v2).
By reinstalling the softwares which where causing errors, I got almost my box working as before. But still, Windows Update does not work, Windows Defender neither and I cannot reinstall those. I tried to reinstall Windows without loosing applications and settings by running setup.exe, but it seems to need a working Windows Update component, which is currently broken.
I didn't reinstall Acrobat 8 yet, thus the error in the event log, but it's a minor problem I can address later.
So, you want a BSOD ? I renamed the file system32\drivers\vmsProxy.sys.old to its original name. I rebooted and BSOD with error 0xc000007b on that file. This one (or one dependence) is obviously corrupted but non essential to boot if removed.
Then I rebooted on my fresh partition to see what happened. There is no Windows\Minidump on the faulty partition. Is there anything I can do before I rename the faulty file again to .old ?
