My Dell 7040 Windows 11 desktop computer was running fine when I turned it off yesterday, but I have problems today.
The monitor shows the wallpaper and taskbar but no desktop icons.
Hovering over a button for a program on the taskbar which has been opened will show a thumbnail of the program as it should be, but it won’t fill the monitor screen.
If I access this desktop via Windows remote desktop everything is working fine.
Restarting didn’t do any good [a couple times I got totally blank screens].
A similar thing happened on my laptop yesterday. I had had it in sleep mode and when I started it again, there was only the wallpaper there. No task bar, no icons. Rebooting fixed it for me, though.
I had that happen several times in Windows 10 (or earlier). Killing the explorer.exe process in task manager always fixed this problem without needing to reboot.
