Windows 10

Windows 10 license keys for Home, Professional, Professional Workstation and Enterprise, plus Professional OEM. The OEM License stays with the first computer you activate it on and isn’t valid for upgrading Home to Pro. The others are RETAIL Licenses: one key activates Windows once, online.

Microsoft ended support for Windows 10 on October 14, 2025, and it now gets security updates only through Microsoft’s Extended Security Updates (ESU) program. Check the system requirements tab on each product page before you buy. Upgrading from Windows Home (not Home Single Language)? Choose Windows 10 Professional with a RETAIL License, not the OEM one. Our guide, How to Upgrade Windows 11 Home to Pro, also covers Windows 10. Looking for the current version? Browse Windows 11 license keys.
