I have never registered my Windows program. I have lost the software. Is there anyway you could find my product key # ?

The product key for windows it is usually printed on a sticker on the cabinet of your computer (if it is a desktop), or at the back of your laptop. And it is required when you install Windows. If you do not put the key windows usually does not install. Some windows version get the key automatically from setup program. If you bought windows disk sparately from computer, then the key may also be on a sticker somewhere in papers/booklets coming with disk (usually booklet).
On many windows versions You have to authenticate Windows after 15 or 30 days. If this is the case, then you do not need the serial again. All you need is performing authentication procedure. If you are experiencing problems I suggest to perform straight the authentication by phone procedure.
A screen will pop up asking you to authenticate your product. Select your location and phone authentication option. You will be given microsoft toll free number for your area. Call them and follow phone instruction to authenticate.
If you fail try it again, eventually use phon option to get assistance from a human cistomer support, as authentication procedure by phone is also fully automated.
