Best for: Anyone who wants the most future-proof Windows license — transferable, with the full Pro feature set.

Retail vs OEM:
This key moves with you. Upgrade to a new PC — transfer your license, no repurchase needed. OEM is cheaper but permanently locked to the first machine it activates on. If you plan to upgrade hardware in the next few years, Retail pays for itself.

Do you actually need Pro or is Home enough?
Pro is worth it if you:

Travel with a laptop and want BitLocker to protect your data if it’s stolen
Need Remote Desktop to access your PC from another location
Connect to a company or school domain network
Run virtual machines with Hyper-V

If none of those apply, Home does everything you need at a lower price.

What Pro adds:

BitLocker — full-disk encryption to protect your data if your device is stolen
Remote Desktop — access or share your PC remotely
Domain and Azure AD join — for business and enterprise environments
Hyper-V — run virtual machines locally
Windows Sandbox — test software in an isolated environment
Group Policy management

How this key works

Online: enter the key and Windows activates over the internet. Microsoft then remembers this PC (a digital license).

Reinstalling

Reinstall the same edition and connect to the internet — Windows reactivates by itself. If setup asks for a key, choose I don't have a product key.

New computer

Yes. Retail moves with you: stop using it on the old PC and enter the key on the new one. Tip: sign in to Windows with your Microsoft account so you can reactivate after a hardware change (Settings → System → Activation → Troubleshoot).

Frequently Asked Questions

OEM keys are tied to one motherboard permanently and cannot be transferred. Retail keys can be moved to a new PC by deactivating on the old one first. Retail costs more but offers hardware flexibility.

Send our support team your order number and a screenshot of the activation error. Most problems are an edition mismatch or a typo, and we'll help you fix it. If the key really is faulty, we send a free replacement within 24 hours — or a full refund if we can't replace it.
