I've come across this glitch a couple times before and it just happened to my work computer again. What happens is when you used the WindowsKey+d shortcut it glitches and opens tons of windows, for what mainly looks like background processes. It doesn't affect the running of the computer, just means I need to sort through all the windows to find the actual program. Has anyone else come across this glitch? And does anyone know what is going on?

Here's a screenshot:


I can't select half of the windows, and of those I can select I can't close many of them. I'm not really game to either as I figure most background tasks are pretty important.
