Windows 11 Keys & Windows 10 Keys – Genuine Product Keys from $24.99

Buy a genuine Windows 11 key from $29.99: a Windows 11 Home or Windows 11 Pro product key is $29.99 for one PC, a Windows 10 Pro key is $24.99 (and also activates Windows 11 Pro), and every key is emailed in about 60 seconds. Microsoft's US store lists Windows 11 Pro at $199.99 (checked November 2026).

Every Windows 11 product key and Windows 10 key sold by Nerdused is a one-time purchase for the PC it activates on. There is no subscription and no renewal, the key activates online with Microsoft, and you can reinstall Windows on that same PC as often as you need and it will activate again. Our 30-day refund promise applies to every order: a full refund within 30 days if your key has not been used or will not activate.

Which Windows 11 key or Windows 10 licence do I need?

Most buyers want a Windows 11 Pro key: it adds BitLocker drive encryption, Remote Desktop hosting, Hyper-V, Windows Sandbox, Group Policy and domain or Microsoft Entra ID join. A Windows 11 Home key covers a family PC or gaming rig at the same $29.99 single-PC price. A Windows 10 Pro key is the cheapest route to Windows 11 Pro, because the same key activates either version on a compatible PC.

Windows 11 needs a 64-bit processor with two or more cores at 1 GHz, 4 GB of RAM, 64 GB of storage, UEFI with Secure Boot and TPM 2.0 (Microsoft's Windows 11 specifications page). If your PC cannot meet that, Windows 10 Pro or Home still installs and activates, but Windows 10 stopped receiving free security updates on 14 October 2025. Still deciding between editions?

If Windows Setup offers an "N" edition, Windows 11 Pro vs Pro N explains why the standard edition is the one to install.

Is a cheap Windows 11 key genuine?

A $29.99 Windows 11 key is genuine when it is a real Microsoft product key sold to one buyer only, stays activated, and comes with a refund if it fails. Nerdused is a member of the Microsoft partner program (ID 6467441), and the licence is for the PC it activates on, and every key is covered by the 30-day refund promise. The keys to avoid are ones sold for a few dollars with no company behind them, which are usually volume keys that activate for a while and then show error 0xC004C003 once Microsoft blocks them.

Buying a Windows 11 key in the UK

The key activates a UK English install of Windows 11 Home or Pro exactly as it does anywhere else, because the keys we sell are not region-locked.

Windows 11 key FAQs

How much is a Windows 11 key?

A genuine Windows 11 Home or Pro key is $29.99 for one PC at Nerdused, against $139.99 for Home and $199.99 for Pro on the US Microsoft Store. Three- and five-PC packs bring the per-PC price lower.

Is a Windows 11 product key a one-time purchase?

Yes. You pay once, the key activates Windows 11 on that PC for the life of the PC, and there is no subscription or renewal. You can reinstall Windows on the same PC and activate again with the same key.

Can I use a Windows 10 key to activate Windows 11?

Yes. A Windows 10 Pro key activates Windows 11 Pro, and a Windows 10 Home key activates Windows 11 Home, as long as the PC meets the Windows 11 requirements. That makes the $24.99 Windows 10 Pro key the cheapest way to a Windows 11 Pro licence.

Which Windows 11 key do I need, Home or Pro?

Home is enough for a family or gaming PC. Choose Pro if you need BitLocker, Remote Desktop hosting, Hyper-V, Group Policy, or to join a company domain or Microsoft Entra ID. Both are $29.99 for one PC, so Pro is the safer pick if you are unsure.

How quickly does the Windows 11 key arrive and what if it does not activate?

The key is emailed in about 60 seconds. If it has not been used or will not activate, you get a full refund within 30 days, and support is available by live chat and email first.
