Microsoft Windows 10 Pro is the business edition of Windows 10, with BitLocker, Remote Desktop, Hyper-V and Group Policy on top of everything in Home. Buy a genuine Windows 10 Pro product key for one PC. It's ideal for older hardware that can't run Windows 11, or for matching existing Windows 10 machines.
Microsoft ended Windows 10 support on October 14, 2025. Home users can get one extra year of security updates through Microsoft's Extended Security Updates (ESU) programme, until October 13, 2026. Windows 10 keeps working after that, but without security fixes.
Good to know: a Windows 10 key generally also activates the same edition of Windows 11 on compatible hardware, so you can move up later.

Unlike Windows 11, Windows 10 doesn't need TPM 2.0 and runs on older PCs, which is the main reason people still buy it.
