Re: Control Panel Isue
To find out which files may be involved you can open an Administrative command prompt (Winkey and type cmd then CTRL+Shift+Enter) and enter the following. You can type it or copy and paste to the command window by right clicking and selecting paste.
findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >%userprofile%\Desktop\sfcdetails.txt
The command will produce a text file and place it on your desktop. You can zip it and attach if you want. If you would prefer to check the log yourself, look near the end and see if it lists which files cannot be replaced/repaired.
This website goes into how to replace files if you need to do so. This process can be complicated but having another Windows 7 install might help in obtaining replacement files.
