You will need the XP disk... go to Run and type in:
"sfc /scannow" (without the quotes and a space after sfc)
Hope this helps. It should replace any missing or corrupt system files.
i did a dumb thing.i deleted services.msc...what must i do, to get it back....what happen was,when i type in services.msc in the run box,windows would come up and it said cannot open this file.it wanted me to pick from a list to open it and i tried that, but nothing would open it.so i thought i would deleted and download it from microsoft.i made the wrong move on that.so what do i do now, how do i get it back....please help!!!!!!!...i`m running XP
