Got your Windows whacked by a virus ? Especially antivirus like Norton and Avira are especially brutal towards the viruses and even nuke out the system files of windows.Bang comes the error dialog regarding a missing windows file or a dll.And as a last resort,common users tend to format their windows installation . However,If an essential Windows file gets deleted by a virus or otherwise corrupted,you can restore it from the Windows CD.
Here is how to do it -
- Search the Windows 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
- for example: 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.
- Replace the file or exe with the one found in Windows CD. And restart to see the changes.
