Before you buy, please read:
- This is only the Windows OEM product key
- Cannot be used to directly upgrade from an older operating system
- Requires a clean installation, and all prior data must be backed up
- Will not allow for a change to a different motherboard model or hard drive once installed

What does OEM mean?
OEM product keys are priced lower than their retail counterparts, but use the same software as retail versions of Windows. Per Microsoft’s EULA regarding OEM, the product key is tied to the PC motherboard which it’s initially installed on, and there is typically no transferring the key between PCs afterward.

Can I directly upgrade from an older operating system?
No, you cannot. A clean installation is required.

What is a clean installation?
A clean installation means formatting your hard drive before installing Windows, so make sure that you have backed up your files.
