I upgraded my PC from 8.1 and I had a black background for the login screen before and after I had upgraded it had grandfathered that background color.
Now that I did an in-place upgrade (to fix some bad windows files), it seems it has taken on the default blue since I have accidentally changed themes. I can't seem to find my old theme from 8.1, or change the background color without changing the accent color.
In 8.1 I was able to set a whole wack of colors to different things, including the login screen independently from the accent color but now it seems impossible
So, how do I change the color on the login screen?
