It's insecure (in more ways than one) to be running Windows in general. If you value security to a high degree you probably shouldn't be using Windows.
Well, security doesn't matter for a media device like that. The exposure is so minimal that it might as well not exist.
Hell, considering I really only use it to pirate shit maybe once a month nowadays, my main desktop PC isn't even on enough to matter; I could keep any old OS on it.
I've been forced to install Windows 10 on my brand new build because it doesn't support W7.
But Steam is also dropping W7 support by the end of this year anyway. Yes, there are native Linux games on Steam and there's also Proton and WINE, but it's not a 100% solution.
Well, I was hyped for Baldur's gate 3, and I may still end up getting it, but I'd have to upgrade too much hardware to play it, and there's really no other games that I'm interested in.
Musicbee is the main reason I'm still running 7 on that pc rather than some flavor of linux. If it ever gets a port, or actually starts working right via wine, bye bye windows for me.
MusicBee is excellent, but I gave up on it to switch to Linux. Also, I've started to fall in love with simple players which depend on folder structure rather than a database, although I suppose one might miss the customisation with MusicBee
