My girlfriend sent me out to buy basil for soup... Had no choice so I went. At the mall entrance, 4 interactive digital signage panels. Used one to check for the supermarket's locations and saw that a display corner was flickering. The app was grabbing the full screen but had a bug with the windows' task bar. Messed with it a couple of minutes, stopped app and... Surprise! Windows 7, logged as administrator... I had to go to disk management... I really had to.

PS: gf said that I should be ashamed of what I did...
