Recover a Corrupted System File

Recover a Corrupted System File
If an essential Windows file gets whacked by a virus or otherwise corrupted, restore it from the Windows CD. Search the CD for the filename, replacing the last character with an underscore; for example, Notepad. ex_. If it's found, open a command prompt and enter the command EXPAND, followed by the full pathname of the file and of the

desired destination:
EXPAND D:\SETUP\NOTEPAD.EX_C:\Windows\NOTEPAD.EXE. If either pathname contains any spaces, surround it with double quotes.

If the file isn't found, search on the unmodified filename. It will probably be inside a CAB file, which Win XP treats as a folder. Simply right - drag and copy the file to the desired location. In other Windows platforms, search for a file matching *. cab that contains the filename. When the search is done, open a command prompt and enter EXTRACT /L followed by the desired location, the full pathname of the CAB file, and the desired filename;

for example: EXTRACT/L C:\Windows D:\I386\Driver. cab Notepad. exe. Again, if the destination or CAB file pathname contains spaces, surround it with double quotes.
