Buy Genuine Windows Product Keys
Every Windows license at Keys Locker is a genuine key that activates directly on Microsoft's own servers — no cracks, no loaders, no keys you can't verify. Whether you need Windows 11 or Windows 10, Home or Pro, we email the key within minutes of purchase so you can activate and get back to work the same day.
Windows Home vs Pro — which do you need?
Windows Home covers everyday computing: browsing, Office, gaming and streaming. Windows Pro adds what businesses and power users rely on — BitLocker drive encryption, Remote Desktop host, Hyper-V virtualization, and the ability to join a company domain or Azure AD. If you work from home or handle sensitive files, Pro is well worth the small difference.
OEM vs Retail keys
An OEM key is the most affordable way to license a PC you own and stays with that machine. A Retail key can be moved to a new computer when you upgrade — ideal if you rebuild often. Both are 100% genuine and unlock the same full version of Windows; they differ only in transfer rights.
Instant delivery, plain-English activation help, and an activation guarantee — if a key ever fails to activate, we replace it or refund you. It's the cheapest honest way to run a fully genuine, always-updated copy of Windows.
