A Windows 10 Home OEM key is a license for the consumer edition of Windows 10, sold under OEM (Original Equipment Manufacturer) terms. OEM licenses are intended for system builders and PC manufacturers, and they are usually much cheaper than retail licenses.
The key difference is transferability. An OEM license is tied to the first PC it is activated on, specifically its motherboard. If you replace the motherboard or move to a new computer, the license generally cannot be transferred. A retail license, by contrast, can be moved to another PC.
Windows 10 Home includes the core Windows experience: the Start menu, Microsoft Edge, Windows Security antivirus, Windows Hello sign-in, and support for the Microsoft Store and Xbox app. It does not include business features found in Windows 10 Pro, such as BitLocker drive encryption, Remote Desktop hosting, Group Policy, or joining a company domain.
Buyers should know that Microsoft ended support for Windows 10 on October 14, 2025. Home users could enroll in Extended Security Updates for one more year, but no feature updates are planned. A Windows 10 key can still be used to activate Windows 11 on eligible hardware, so check that your PC meets Windows 11 requirements before buying.
