Windows 10 Home OEM licence is still the most practical choice for older computers without TPM 2.0 and for everyday use. The key is permanently registered to your motherboard and stays valid on the same computer for life. Genuine, invoiced and fast: your key is usually in your inbox within 1–90 minutes.
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.
For Windows 10 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.
Microsoft ended mainstream support for Windows 10 on 14 October 2025. Your system keeps working and your licence remains valid for life, but no new feature updates are released. We covered the full roadmap in our guide Windows 10 end of support: what to do in 2026. If your hardware qualifies we recommend moving to Windows 11; for older machines a Windows 10 licence remains a safe, legitimate choice.

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