Well I bought the windows validation kit and already used my key from the email and validated windows to update. The thing is I want to reformat now and am worried that the validation key is only a one time use? Or will I be able to reformat and use my key again? The reason I ask this is because I used system restore after I used the validation key to restore at a point before I validated xp with my new key, I went to windows update to update evrythign again and it gave me this key is already in use, so I was stuck to retsoring back to a point after validation. Will my key only work 1 time or will it work when I reformat? I don't want to reformat and be stuck without a computer and have to buy another os.
Thank you Charles.
