Not sure what I started here . . .
Sometimes I leave my computer running and go away for a couple of hours.
When I return the screen is dark, I then touch a key, and see the Desktop with my usual icons and taskbar, etc. I also see the Start menu, which is the same menu as if I had touched the Windows key.
Prior to Windows 11 24H2 I don’t remember seeing the Start menu in this situation.
Hope this is clearer (but probably isn’t).
