Windows 10 LTSC is common among some enthusiasts. No candy crush or start menu ads, but it still tries to trick you into using an online account during the install if you make the mistake of connecting to the internet when asked, and you still have to change a bunch of privacy toggles. I don't like or trust it, still, I just put it on my parents' machines since they probably would've resisted switching to GNU/Linux and Windows 7 lost support.
