Advanced System Care 5
makes such a mess is reported earlier, too . First what I am to say you that windows 7 does not need any advanced system care at all . All these programs are not enough able to care windows 7 system. The inbuilt disk cleanup utility and CCleaner
is enough for the OS.
Now let us discuss about the fix. If some registry backups are made by Advanced System Care 5
, restore those backups first.
If not fixed yet, follow SFC /SCANNOW Command - System File Checker
Another idea to fix it may be by applying the System Restore
to an earlier date than occurrence of that mess.
If still not fixed, try Taskbar - Change Icon Button Width Size
At the last point, you can always perform a Repair Install
, when no other fixes are working.
