Windows 8.1

Windows 8.1 reached the end of its support on 10 January 2023. Since then it has received no security updates, which makes it a poor choice for a PC that goes online. We therefore do not list Windows 8.1 keys at the moment. This page explains your options; for current products go to all Windows license keys.

• Windows 8.1 support ended in January 2023
• Windows 10 and 11 keys available now
• Free in-place upgrade paths
• Help choosing from our team

• Windows 11 — the current, fully supported version, for PCs with TPM 2.0 and Secure Boot.
• Windows 10 — for older PCs that cannot run Windows 11.

Our system requirements guide shows which your PC can run.
