At some point they had a 6 month trial for Server editions. It was a bit clunky to setup (audio support is not installed by default and I had to dig the old Xbox controller driver for W7 I think) but is otherwise a pretty good experience. Absolutely zero bullshit features installed and never changes things on its own.
The only issues I had were the version check of the Oculus installer (praise the soul on reddit who described how to bypass it with dnSpy), and some COD game refused to work on it too (too old, maybe it wanted a newer feature update).
