Windows 7: Audio driver corrupting bootcat.cache file causing Stop 6b at boot

Audio driver corrupting bootcat.cache file causing Stop 6b at boot

What would cause a driver update to modify and corrupt the bootcat.cache file resulting in a Stop 6b error during bootup? I'm confident it's related to the Realtek audio driver. Initially, I can successfully reboot the PC and everything will appear fine, but after sometime the bootcat.cache file will change. I try to check the file intermittently to see if or when it changes so I can restore my good copy. If I don't restore the original good copy, on the next boot, Windows will not load and gives me the dreaded Stop 6b error. To get back into windows, I restore the good copy that I have backed up now just for this issue. What I find strange is that if I delete the bootcat.cache file, Windows is suppose to recreate it during boot, but it never does. I figured it would at least create the same bad version of the file. Also, the ntdll.dll file is present.

Any suggestions to pinpoint what is exactly causing the bootcat.cache file to change, and why Windows will not recreate it during boot if I delete it?

Thank you
Mike

Thank you! I did and it completed successfully. I'm certain I had ran the Readiness Tool before, though Windows doesn't seem to show it as installed when I did a search for KB947821 under the View Installed Updates in Program and Features, before and right after I just installed it.

TheCheckSUR.log shows I have 208 CSI Missing Winning Component Keys. Not sure how to resolve those.

I uploaded the CheckSUR.log if that helps

The files that are missing need to be copied from the right source, the copied files are placed on a specific location, you run SURT again and it should fix the issue. That is the process I've seen in posts like Windows 7 Service Pack 1 won't install (error code: 800B0100) - Windows 7 Help Forums

It is best if you create a new thread at Windows Updates Activation - Windows 7 Help Forums for this, post the CheckSUR log there.
