I discovered that pop up for case, so I tried to follow that steps and download directly to see if it could help, we will see in the day.
Just minutes ago I have some STRANGE behavior of windows. This happen:
for some reason I couldn't maximize the tab I minimized, if I click on tab it try to launch the application again like I was doing in the short cut on the desktop. For example, let's say that I'm running Skyple, and I click the tab reduced/minimized, if I click it launch another login panel to login, or something similar, internet explorer tab minimized, I click it and was launching a new IE not that tab minimized... while if I go with rollover of the mouse on the tab and I see the preview it came back on the screen, just on the click it had this strange behavior. I decided to restart so windows.
When I did I had a blue screen with 4 big icons 1 sayd Exit and continue with windows 8.1, another saying if I want to start a recovery, other 2 I don't remember, something like that, I could make a print screen, I could make a photo with mobile.
Happened to you this sometime? strange behavior, I was a bit scary.
Update: now that I remember, happened that I had 2 photos on the desktop and one got stuck and I couldn't open or delete and was saying "photos" that couldn't open it, so may be that this caused some crash of windows and unresponsive behavior. Now that I think to it I think that caused some issue. Now it's all fine after reboot.
