Installed Windows 10 Pro using an existing CD. Purchased license key from Gamers Outlet. Entered key, Windows now activated. Worked perfectly. Thank you.

Works like a charm Thank you.

Had an initial issue with the key, but got resolved very quickly through immediate-response emails, with a very pleasant and helpful attitude. What great customer service! Very happy.

Very smooth transaction. After purchase instant got my CD KEY and work perfectly. Thanks a lot.

I must say I was wary of this because it was so cheap - but it worked straight away - thank you
