This can be problematic because if you have gotten the free upgrade to Windows 10 and then you replace a bunch of parts on your computer after July 29, 2016, you will end up with a non-genuine version of Windows. It only works with the current hardware on that computer. If your Windows 10 license is based on a Windows 7 or Windows 8.1 license (even a retail license) and you have to replace the motherboard on your computer, Windows 10 will no longer be activated. If you have a retail version of Windows 10, you will be able to move it to another computer even after July 29th. Right now, you could reinstall Windows 7 or 8.1 on another computer and then perform the free upgrade to 10.
In order to upgrade from Windows 10 Home to Pro, you still would need to pay $99, which is what Microsoft is currently charging.Īnother thing to note is that if you upgrade Windows 7 or Windows 8 to Windows 10 or if you have an OEM version of Windows 10, after July 29, you will not be able to move that copy of Windows 10 to another computer.
Above is a table that explains which version of Windows 10 you will have depending on which version of Windows 7 or Windows 8.1 you currently have.
