I’d suggest Windows 10 Enterprise LTSC if you’re sticking with M$. It’s the least bloated and least intrusive modern OS. You should see improvement in battery life and your devices can use the same drivers. The official MSDN ISOs aren’t hard to find. Then find “massgravel” on GitHub and you can pretty easily figure out permanent activation via HWID.
