Hello Ashakaren and welcome to Seven Forums.

You could try doing a System Restore and roll back your computer to a date/time prior to changing things.

You could also try running a System File Checker scan from an elevated command prompt (Option Two.) The sfc /scannow command (System File Checker) scans the integrity of all protected Windows 7 system files and replaces incorrect, corrupted, changed/modified, or damaged versions with the correct versions if possible.
