I ought to log into Windows now and again just to get the updates, but I just don't need it. We use Windows at work, but a lot of that could use Linux.
19.04 is supposed to have some performance improvements, but it's not feeling too different so far. The look of it changed a little in 18.10, which I only used for a couple of days before upgrading again. Overall it is all very stable and usable.
My Upgrade notification popped up today and I'm now dancing with Disco Dingo too.
Good idea to boot up Windows every now and then just to keep it up to date, even if you don't use it often.
Otherwise, when you do need it, you may find it lagging while it tries to get up to date in the background making the task you needed to do frustratingly slow or close to impossible.
I've hardly used Win10. Still on 7 at work. I've just not had a need to use it at home.
