Important information before purchase

Windows 8.1 is no longer supported by Microsoft: no more security updates are released for this system. We do not recommend using it as a main workstation connected to the Internet. This licence meets specific needs, listed below.

The uses for which this licence still makes sense

• Hardware from the 2012-2015 period — tablets and ultraportables whose drivers were never provided for Windows 10 or 11.
• Virtual machines — recreating an 8.1 environment to test software compatibility.
• Business software certified for Windows 8.1 — on a workstation kept off the network or heavily filtered.
• Computer-controlled equipment — kiosks, terminals and devices whose control software has not evolved.

What the Pro edition offered

• BitLocker and BitLocker To Go — encryption of the disk and removable media.
• Incoming Remote Desktop — the workstation accepts incoming connections.
• Hyper-V client — built-in virtualisation in 64-bit.
• Domain join and group policy — integration into a corporate directory.
• Booting from a VHD and EFS encrypting file system.
• Hybrid interface — tiled Start screen, Start button, direct boot to the Desktop and unified search.

Activation

The activation key reaches you by email within 24 hours maximum. Enter it during installation or from PC settings › PC and devices › PC info › Change product key. Activation by phone with Microsoft may be necessary on this system.
