Hash mismatch

Anonymous

Does anybody know how to fix this problem? It is related to a Windows 8 64-bit platform and seems to be rather common (see Web results for "Amd64\CNBJ2530.DPB" of prncacla.inf*"*).

No apparent malfunctions, but very slow startup, especially the first one at morning.

Below what appears in the CBS.log after multiple sfc /scannow(s) that say it is impossible to repair some damaged files.

I found something very interesting here:

http://social.technet.microsoft.com/Forums/en-US/w8itprogeneral/thread/26f35def-6f55-4c07-9ba8-73e2d402e6cc

I am going to try the dism /online /cleanup-image /checkhealth command and see how it goes.

L.E. Actually, there are 2 commands to run:

dism /online /cleanup-image /checkhealth

dism /online /cleanup-image /restorehealth

I will be back with the results.

Very Late Edit:

There is also a tool I found recently that helped me solve this issue in Windows Server 2012 R2.

The above commands didn't work so I ran this tools and it solved the problem. You can download the tool here:

I have been checking this issue through other Microsoft Communities (England, France, Italy). According to many experts the problem is not significant. Moreover, looks like sfc often reports false errors. Both my PCs (1 laptop Windows 8 Pro 64-bit and 1 desktop Windows 8 32-bit with Media Center) report the same "hash mismatch" but don't seem to show any malfunction. No Canon printers installed! I hope that Microsoft will solve this mystery ... sooner or later.

This does work. However, I'm running Windows 8.1, which seems to use different dism commands. Either that, or the commands have changed.

I entered the following command exactly as written here: DISM.exe/Online /Cleanup-image /Restorehealth

Thanks for posting this solution. I am also running Win 8.1 and encountered this issue. Your suggestion worked for me.

It is interesting that the original post was 22 months ago, and this issue is still happening...
