I just upgraded from 10049 to 10061 using Windows Update and found that I cannot launch apps I have pinned to the Start Menu. 'This PC' was the first I tried and then several folders and applications I use often do no open when I try to open them from the Start Menu. I get a brief blink and nothing happens. They all open happily if I do so through File Explorer. Is this a problem with 10061 or, most probably, am I doing something wrong?
