1) Delete CBS.log inside C:\Windows\Logs\CBS

2) Note: windows installation/repair cd could be necessary.

Launch sfc /scannow from an elevated command prompt, wait until it finishes (15-50 minutes), check the final result (note it down).

If it says no integrity violations (or something similar), stop here... Otherwise restart your machine and relaunch the tool. Then, report both final results here.

3) If both results says that there are damaged files and it can not restore them, post here the CBS.log file (upload it using the forum feature or a website where you could upload files).
