Fix : Stop Error 0x0000006B Process1_initialization_failed BSOD in Windows 7

This post will help you fix an issue with your Windows 7 computer, where your computer might not start up and crash before the login window appears. You might also get a blue screen error with the error code 0x0000006B. The whole error code would be something like this:

According to Microsoft KB article 981933 this error is caused by a corrupted bootcat.cache file in “ %systemroot%\system32\codeintegrity” folder.

  • Go to Start Menu & type Windows update
  • Click on Windows update from the search results

I’ve done that with a linux based live cd by mounting windows partition, as I didnt see bootcat.cache in command prompt.
After deleting bootcat.cache and reboot the same issue occures without any changes.
I’m running Win7 Enterprise x64.
If you have no answer for this and I’m not able to find anything, unfortunately I have to image this machine.

So now… I fixed it!
I just copied the bootcat.cache from another Win7 machine to the directory.
Hope this helps other users.

I appreciate for your help I recently had a blue screen of death on my windows 7 32bit laptop. The method 2 worked well for me so thank you very much.
