Windows 7 Validate whether a sealed Win7Ultimate is genuine?

[pwiklund]

Is there any way to determine whether a seemingly factory-sealed copy of W7Ultimate I have obtained from a private re-seller is genuine and not previously registered?

Would be really nasty to go all the way and install it just to find out of any problem...

Thanks in advance!

If you already paid for it, you might as well just try it. You won't be running into trouble during installation because you can skip typing the product key during installation. You can always enter the product key after installation. The only problem is it won't get validated if you have an invalid key but you can use the OS for 30 days..

Thanks for the suggestion - I had just hoped there was a way to check it in beforehand.

Are you sure that this not a scam. The prices look too good to be true.
