Updating your Windows 10 setup Transferring your Windows 10 system Changing your Windows 10 installation
Purchased a Windows 10 OEM key in 2015 and are now assembling a new PC for my sister. Can I transfer the Windows installation so it runs activated on the new machine? I’m okay with using an unactivated version and don’t mind skipping the old setup. Should I simply copy the key, reuse the same Microsoft account, or create a new installation media on the specific computer?
The key is tied to your motherboard, so swapping it means the license can't be moved. It only works with retail licenses—better grab a cheap $20 key from a site and use that instead.
Unless you're reusing the same motherboard, the Windows 10 OEM license won't apply. A regular retail key purchased from Microsoft or their authorized partners would work on the new build regardless of the motherboard used.
The process of replacing a motherboard without losing important data is achievable, as explained on the Microsoft website. Many users have already addressed this issue before, sharing their experiences on forums. OEM activation remains active after hardware modifications.
Official instructions from Microsoft explain how to reactivate Windows after hardware changes. You can switch motherboards and keep the existing installation tied to your Microsoft account. The advice isn't about transferring Windows from a laptop to another device or trying unconventional methods like eating a cake. My perspective aligns with the guidance provided, emphasizing that using the same motherboard is necessary for valid licensing. Any other approaches aren't supported or recommended.
