What OS are you running? if win 8/8.1 or 10 you can just use the "Recovery" option where it removes all you files (installed software and data) then it re-installs windows, if your running 7 you can use sysprep.exe.

im using windows 8.1, but i dont have the CD, is the cd necessary to recovery windows 8.1?

the recovery cd is the same as the recovery partition in windows, usually you don't need it as windows automatically creates one (esp for pre installed systems).
you can create a recovery cd then use the "recovery cd" to reset windows.
