I've been using windows 11 for six months. when I hover over the taskbar, a phantom windows explorer window appears, but it's not clickable and it disappears when I move the mouse away. my right hand monitor has a white box with a small 'no' symbol in it stuck in the middle of the screen. it doesn't seem to derive from any running application and I cannot get rid of it. on the windows 10 install I ran before, the task manager totally stopped working, it just froze every time I opened it. I run Linux on all my other machines and stuff does go wrong, but it goes wrong in ways that make sense to me and which I can fix. on windows people just tell you to run sfc scannow and reinstall if it doesn't work. that's no way to live your life.
