Uninstall Xbox one games and reinstall later?

If I have a game deinstaliere dasbich bought in the store, I have to buy it again if I reinstall it?

And how is it to play with the 360s when I got them with Gold Ultimate, can I reinstall them after the expiration?

So far as I know the game is after the transaction of yours even if the game was free. This means that you can then install and uninstall it as often as you want it is tied to your account. Does not apply to games of the xbox game pass, I think

What you have bought and paid for is yours.

Super, then I can safely create space on the hard drive? That means also the 3 to 4 games which are offered free of charge for Goldmembers every month can I also install after the abo?

Yes, as long as you have gold
