An OEM (Original Equipment Manufacturer) licence registers the operating system permanently to a single computer. The key pairs with your motherboard on first activation, so when you format or reinstall Windows on the same machine it reactivates automatically. There is no subscription, no yearly renewal, no extra fee — pay once and use it for the life of your device. If you are not sure which edition fits you, see our guide Windows 11 Pro vs Home: the key differences.
For Windows 11 Home we offer several licence types including OEM (this product), MAK and Retail — and the catalogue keeps growing. All of them are 100% genuine; the difference is the usage scenario:
| Feature | OEM (this product) | MAK | Retail |
|---|---|---|---|
| Device binding | Permanently tied to the motherboard | Not permanently tied to a device | Tied to the user |
| Moving to another PC | Not transferable | Not transferable | Transferable |
| After a format | Reactivates automatically | May need reactivation | Easily reactivated |
| Validity | Lifetime | Lifetime | Lifetime |
| Price | Mid-range | Most economical | Premium |
| Best for | Keeping one PC for many years | A fast, economical solution | Frequent hardware upgrades |
We examined all the details in our guide OEM vs Retail licence differences.

No. Because the OEM licence is paired with your motherboard, Windows reactivates automatically as soon as the same computer goes online after a reinstall.
