How to Transfer Your Windows License to a New PC
Whether you can move Windows to a new PC depends on the license type. Retail licenses are generally more flexible, while OEM licenses are usually tied to the first device. Before rebuilding or replacing a computer, confirm what you own.
Identify the license type first
Check whether your Windows license is Retail, OEM, volume, or tied to a digital entitlement. The label matters more than the product key format.
Prepare the old PC
Back up files, record your edition, sign into the Microsoft account used for activation if applicable, and make sure you are not trying to activate a different edition on the new PC.
Activate the new PC carefully
Install the same edition you are licensed for, enter the key when prompted or after installation, and use activation troubleshooting if your license is linked to your account.
Common questions
Can I transfer an OEM Windows license?
Usually no. OEM licenses are normally tied to the first computer they activate on.
Can I use a Windows 11 Pro key for Windows 11 Home?
Use the edition that matches your license. A Pro key is intended for Pro activation, not Home.
