Why does vmconnect.exe require run as administrator?
If I start "Hyper-V Manager" from start menu and then in it connect to a VM, it never asks for Administrator rights (the UAC dialog never appears).
I selected "Solid color" for background and then clicked a color (blue-something) in the 2 dozen offered colors.
I haven't rebooted since, so I don't know if the setting will work after that.
I have the same problem. Sometimes the title bars ignore the accent color setting, sometimes it is used.
I have Windows 11 22H2.
Now the setting works, here is a screenshot of Explorer:
