So yesterday, these started appearing in my taskbar (running the Windows Consumer Preview, by the way). Tons of windows that have the default executable icon and when Aero peek is activated on them, nothing shows up. The moment I click the taskbar, click/right click them, or even open task manager they instantly disappear. They eventually start reappearing one by one.
It almost seems like malware-type behavior, but I've scanned a few times and neither Windows Defender nor AVG has found anything. Any ideas?
