Windows 8.1 Professional for older hardware
Windows 8.1 Professional is a lightweight option for older computers that struggle with newer Windows versions, and for keeping legacy applications running. KRBKeys provides a genuine Windows 8.1 Pro key for 32-bit and 64-bit installations, delivered by email with the official download link. Windows 8.1 Pro includes BitLocker, Remote Desktop, Hyper-V and domain join.
Keep in mind that Microsoft ended support for Windows 8.1 in January 2023, so it no longer receives security updates. If your PC meets the requirements, Windows 10 Pro or Windows 11 Pro are the supported alternatives, both available in our store.
