Windows 11 Pro OEM – Activation key tied to the motherboard

Windows 11 Pro under an OEM licence equips a workstation with the professional edition of the system, in the most economical licence format. It is aimed at freelancers, small businesses and advanced users who need to encrypt their data, control their machine remotely or attach it to a corporate directory. Point to know: an OEM key ties itself permanently to the motherboard of the activated PC; it is not transferable and a replaced motherboard invalidates the activation.

What the Pro edition brings

• BitLocker — full disk encryption, essential on a laptop.
• Inbound Remote Desktop — taking control of the workstation from another computer, impossible in the Home edition.
• Hyper-V — virtual machines run locally on the workstation.
• Windows Sandbox — an isolated environment wiped on closing, to test a suspicious file.
• Domain join and group policies — integration into an Active Directory or Azure AD infrastructure.
• Windows Update for Business — deferral and scheduling of feature updates.
