Windows 11 Pro OEM vs Retail: Which One Fits You?
An OEM Windows 11 Pro key activates one PC and stays tied to its motherboard, which makes it the cost-effective pick for the machine you keep. A retail key can move to a new PC later and comes with Microsoft direct-order proof — see the Windows 11 Pro Official (retail) edition if you rebuild or resell PCs. Both unlock the identical Pro feature set: BitLocker, Remote Desktop host, Hyper-V and Group Policy. Still weighing the move up from Home? The Home to Pro upgrade guide walks the whole path.
How to Activate Your Windows 11 Pro Key
After checkout the key arrives by email within minutes. Open Settings > System > Activation > Change product key, enter the 25-character key and restart — Windows upgrades and activates in place, keeping your files and apps. The full walkthrough lives in our Windows 11 activation guide, and if you are moving up from Home, the Home to Pro upgrade guide covers the edition switch plus fixes for errors 0xc004f050 and 0xc004f069.
