Windows 11

Windows 11 is the current version of Microsoft's operating system and the one we recommend for any computer that meets its hardware baseline. A Windows 11 license key activates it permanently on one PC, whether you are doing a clean install or upgrading from Windows 10. This page is part of our wider Windows license keys range.

• Windows 11 Home and Windows 11 Pro keys
• Perpetual license — no subscription
• Works for clean installs and in-place upgrades
• TPM 2.0 / Secure Boot ready systems
• Activation guide included
• 10-day replacement guarantee

The two editions share the same modern interface; the difference is in the tools around it.

• Choose Home for personal use — study, entertainment, family PCs and gaming. It is the most affordable route to a fully genuine Windows 11: Windows 11 Home License Key.
• Choose Pro if you need BitLocker encryption, Remote Desktop hosting, Hyper-V, Windows Sandbox, Group Policy or the ability to join a company domain: Windows 11 Pro License Key.

Moving a Home PC to Pro later is possible with a Pro key, but buying the right edition first saves a step. Our Windows editions explained guide compares them side by side.

• One genuine Windows 11 product key, delivered by email delivery (usually within minutes, always within 24 hours of payment).
• A perpetual license for one PC with Microsoft's regular feature and security updates.
• Clear activation instructions and a link to our guide on activating Windows 11 step by step.
• our 10-day replacement guarantee, and help from our 24/7 support team.

Windows 11 needs a 64-bit processor (1 GHz or faster, two or more cores) on Microsoft's supported list, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot, a TPM 2.0 chip, a DirectX 12-capable graphics card and a 720p display. Most PCs from roughly 2018 onward qualify. You can verify yours with Microsoft's PC Health Check, and the full list is in our Windows system requirements guide. If your PC falls short, the Windows 10 keys are the alternative — though Windows 10 no longer receives mainstream support.

1. Open Settings → System → Activation.
2. Select Change product key and type the key from your email.
3. Confirm with Activate while connected to the internet.
