Has Anyone Else Had This UAC Prompt Bug Before?

So for some reason this has happened to me a few times on Windows 7, 8.1, and 10. You know how when you go to install a program and the UAC Prompt comes up and it has that faded black effect around the window? For some reason I sometimes get this bug on different installations where the prompt comes up but that effect disappears, the window shows but not the dark effect, ...weird. Has anyone else had this bug before?

Have seen it many, many times over the years. If the computer or whatever controls this pop up doesn't recognize the publisher it will pop this up.

Steam is a digital distribution platform developed by Valve Corporation for purchasing and playing video games.

So when I know the publisher I just click yes and continue. Since I always know what I"m downloading I would guess I have always said yes.

You do what you fell best doing.

Hahaha I found out what the issue was, for some reason it was not dimming my desktop when the prompt displays. In order to fix this I went into the control panel > User Accounts > Change User Account Control Settings, dragged the slider to the second option where it says "don't dim my desktop" saved and then dragged it back to the Always notified option and the dim effect magically appeared again, what an odd bug. Novirusthanks Syshardener might've played around with the UAC controls or something.
