By mistake i have deleted some of my Windows XP System files. Now when I start my computer after booting Windows XP when it comes on desktop and after 1 minute i restarts again what should i do. i am in a great trouble. i have also tried {repaire} function from the original cd of XP booting system but not able to solve the problem please resolve my problem. thanks in advance.
Start up in safe mode (hopefully it won't reboot) and run this command: sfc /scannow If that doesn't fix it, the Windows repair option from the cd should work. Don't press R at the first screen for recovery console. Press Enter to continue and it will search for existing installations, then press R to repair Windows after it finds it.
