I have a few basically clean machines I upgraded from 8.1 to 10 yesterday and on most of them when i try to use apps like the store (which was grey on some of the machines) the apps start then immediately close. Any resolution for this? I was able to remedy it on one by doing another in place upgrade but id rather not as its not really the answer. The app that seems to be giving me the most trouble is the Weather App (msn weather default installed). Thanks in advance!
