Question: When I click on icons in Control Panel, nothing happens. CTRL-ALT-DEL gives me a error message. What is happening?

This is a strange and unique error but I thought it was worth writing about.

For a possible fix to this issue without formatting, please perform the following:

Click Start, Click Run and type SFC /SCANNOW and hit Enter on your keyboard. Once this is done, turn off or reboot your computer.

(If sfc discovers that a protected file has been overwritten, it retrieves the correct version of the file from the %systemroot%\system32\dllcache folder, and then replaces the incorrect file. If the systemroot%\system32\dllcache folder becomes corrupt or unusable, use sfc /scannow, sfc /scanonce, or sfc /scanboot to repair the contents of the Dllcache directory).
