SCAN & FIX CORRUPTED WINDOWS SYSTEM FILES

• IF ANY OF THE WINDOWS SYSTEM FILES ARE MISSING OR ARE CORRUPTED, WINDOWS MAY NOT BEHAVE AS EXPECTED. FOR EXAMPLE, SOME WINDOWS FUNCTIONS MAY NOT WORK, OR WINDOWS MAY CRASH. 

• WINDOWS 7, LIKE PREVIOUS VERSION, HAS AN INBUILT TOOL CALLED SYSTEM FILE CHECKER TOOL (SFC.EXE) WHICH SCANS FOR MISSING OR CORRUPTED SYSTEM FILES AND REPAIRS THEM. USING SYSTEM FILE CHECKER TOOL (SFC.EXE), YOU CAN DETERMINE WHICH FILE IS CAUSING THE ISSUE, AND THEN REPLACE THE FILE.

• Start --> All Programs --> Accessories --> Command Prompt. Right Click & RUN AS ADMINISTRATOR.  

• Type in Command Prompt --> "sfc /scannow".

• The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft Version.
