Windows 8.1 Professional 32/64-bit Product Key Digital license
Microsoft Windows 8.1 Professional – Genuine Lifetime Digital License
This is a 100% authentic product key for the lifetime activation of Microsoft Windows 8.1 Professional in any available language. The license works for both 32-bit and 64-bit versions and is valid for installation on any compatible PC.
Because this is a digital license (not an OEM key), it can be:
-
Used to install Windows on any compatible computer.
-
Reused for unlimited reinstalls on the same PC, even after hardware changes.
-
Linked to your personal Microsoft account for guaranteed lifetime access, even if the key is lost or your hardware is replaced.
Unlike OEM keys that are permanently tied to a motherboard (and often brand-locked to manufacturers like HP, Dell, or Lenovo), this digital license remains flexible, allowing you to upgrade or change your operating system freely in the future.
