Run the System File Checker. To do this, right click on Command
Prompt (Start Menu\Programs\Accessories), and choose
Run as Administrator. Copy the following, and Paste it after the prompt:
sfc /scannow
Press Enter. It will scan all your system files. It may take a few
minutes. If things are okay, you are given the text message "Windows
Resource Protection did not find any integrity violations". If things
aren't okay, it will attempt to replace the bad system files.
