Recovering a corrupted file system

If your PC has been infected by the virus and some of its files in the Windows directory be affected or corrupt, is there anything I can do to recover it without re-PC? ..

If a critical or essential gets whacked by a virus, can be restored from the Windows CD.

* Search the file name on the CD, replacing the last character with an underscore (eg Notepad.ex_). If it is found, open the command line and enter the command EXPAND, followed by the full path of the file and the desired destination:

EXPAND D: \ SETUP \ NOTEPAD.EX_C: \ Windows \ NOTEPAD.EXE

If a route contains some space, surround with quotes ( ').

If the file is not found, find the file name unchanged. Probably be within a CAB file, which seeks to Windows XP as a folder. Just right-drag and copy the file to the desired location.

When searched, open a command prompt and enter EXTRACT / L followed by the location, the full pathname of the CAB file and the name of your desired file, for example: EXTRACT / LC: \ Windows D: \ I386 \ Driver.cab Notebook. Exe

If the destination or CAB file path contains spaces, surround with double quotes.
