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.
