Windows 11 Home to Pro Upgrade

The Windows 11 Home to Pro upgrade key unlocks Windows 11 Pro on a PC that already runs an activated copy of Windows 11 Home — no reinstall, no USB drive, and your files, apps and settings stay exactly where they are. Enter the key, restart, and you have BitLocker, Remote Desktop, Hyper-V and Group Policy within minutes.

What Do You Get When You Upgrade to Pro?

• BitLocker drive encryption — protect your data if your laptop is lost or stolen.
• Remote Desktop host — connect to this PC from another device, which Home cannot do.
• Hyper-V and Windows Sandbox — run virtual machines and test apps safely.
• Group Policy and domain join — join a work domain or Microsoft Entra ID.
