Windows is not “fine” aside from all the non-UI stuff, they’re UI is annoying and slow to me, they moved things behind extra clicks/commands to make it “clean”- stuff I actually use.
And then there’s the whole tracking usage to drop adds in your notification thing… which is a privacy nightmare.
KDE: Welcome to Linux. Do you like the UI of Windows? Well we have an excellent offering for you if that’s your choice. There’s also other DEs that you may select from if that’s your choice.
I wish Microsoft kept Windows as a paid product, instead of making it effectively free (with things like free upgrades from older versions) and sticking ads all over the place.
