OEM key · one PC
A Windows 11 Home licence key. It appears on your order page the moment your PromptPay payment lands — sign in before you buy, because the key only reveals to your account. To activate: connect the PC to the internet, open Settings › System › Activation, press Change next to "Change product key", paste the key, then Next and Activate. The How to buy page has the steps. Before you buy: • Home only. This key activates Windows 11 Home, not Pro. If your PC has Pro installed, it will not activate. • OEM licence. It belongs to the first PC it activates and does not move to another computer (a new motherboard counts as a new computer). • Licence key only — no disc or USB. If you need to install Windows, the installer is free from microsoft.com. Stuck on activation? Message us on LINE with your order number.

Good to know
- An OEM key belongs to the first PC it activates and does not move to another one.
- A key works once, on the account you are signed in to when you activate it, and cannot be moved to another account afterwards. Check whose account is open first.
- Paste the key rather than typing it — 0 and O, 1 and I are easy to mix up.
