OP probably had to update Windows today.
It's a weird world where KDE out of the box is more usable than Windows.
I gave the wrong laptop to my mother a few months back and she only told me when she finished banking that the windows menu looked funny (Like the hacker one you put on the family computer when you were 12.) it was KDE. Usually she asks for help at least once on windows for getting the wifi connected.
The year of desktop Linux was 5 years ago and we didn't even notice.
