Underground And Other Stuff

Every once in awhile, an essential system file of Windows disappears or gets corrupted. No, you don't need to re-install Windows. You can simply restore the file. To do so, put your Windows CD into the CD-ROM, then select Search from the Start menu. Search the CD for the file you are missing, leaving the last character of the filename as an underscore (for example, calc.exe would be calc.ex_). If it is found, open up a command prompt and then type "expand" followed by the full path to this file, a space, then the path where you want it to be sent. If either of these paths has a space in it, surround the path in quotes.
If the file cannot be found, its probably because the file is located in a CAB file. CAB files are like folders in that they contain a bunch of smaller files. I think of them as CABinents, but that's just me. In this case, just open the CAB file in Explorer, find the file you need and drag it to the location you need it.
