Microsoft Windows 11 Pro

Microsoft Windows 11 Pro is the business-ready edition of Windows 11, adding BitLocker encryption, Remote Desktop hosting, Hyper-V virtualisation and Group Policy to everything in Windows 11 Home. Buy a genuine Windows 11 Pro product key here and activate a full retail licence on one PC — delivered instantly by email, with no subscription.

What Does Windows 11 Pro Add Over Home?

Windows 11 Pro includes every Home feature plus the tools professionals, IT admins and power users actually rely on:

• BitLocker drive encryption — full-disk encryption for internal and removable drives, with recovery keys you control.
• Remote Desktop host — connect to this PC from anywhere. Home can only connect out, not accept connections.
• Hyper-V and Windows Sandbox — run virtual machines and test untrusted apps in a disposable, isolated desktop.
• Group Policy and domain join — manage settings centrally and join Active Directory or Microsoft Entra ID.
• Windows Update for Business — control when feature and quality updates install.

Already running Windows 11 Home? You don't need a clean install — our Windows 11 Home to Pro upgrade key unlocks Pro in place, keeping your files and apps.

Windows 11 Pro FAQ

Can I upgrade from Windows 10 Pro to Windows 11 Pro with this key?

Yes, provided your PC meets the Windows 11 hardware requirements. If your Windows 10 Pro is already activated, the in-place upgrade is usually free; this key is for new builds, clean installs or PCs without a valid licence.

Is this a subscription?

No. It is a one-time purchase that stays activated on your PC and continues to receive Windows updates.

What if my PC doesn't have TPM 2.0?

Most PCs from 2018 onward have firmware TPM (fTPM on AMD, PTT on Intel) that just needs enabling in the BIOS/UEFI. Check this before buying if you're unsure.

Can I move the licence to a new PC?

Retail licences can generally be transferred to a new PC once removed from the old one. If reactivation fails after a hardware change, our support team will help you get it activated.

I got an activation error — what now?

Most activation errors come from an edition mismatch, for example Windows 11 Home installed but a Pro key entered. Contact our 24/7 support with a screenshot and we'll resolve it — or replace the key under our warranty.
