My SO bought a computer from Gateway which originally came with a copy of Windows 7 installed. She did not keep the OEM install disk when she received the desktop.
After her OS crashed, I attempted to reinstall with a copy of Windows 7 that I purchased independent of the OEM manufacturer. It was a legitimate version, but because it was not Gateway's version, the hardware insists that the OS is not "genuine".
The problem is that the Gateway is out of warranty, and Microsoft can't help (I've called their tech support). To get a copy of Gateway's OS, I would have to pay something like $100+ to access their tech support, and get a key that agrees with their hardware.
However, Windows 10 has recently been released, and upgrades on it are also $100+ dollars. I would prefer to just buy Windows 10, and circumvent Gateway entirely.
My questions is: if a legitimate copy of Windows 7 does not cooperate with the hardware, how can I know if a legitimate copy of Windows 10 will cooperate with the hardware? I'm concerned that if I just buy a copy of Windows 10, that Gateway will still want their cut, and their hardware will tell the OS that it's not a legitimate version.
