A couple of nights ago our windows apps stopped loading in our laptop. We ran a bunch of things suggested by HP tech support to no effect. We found and ran tweaking and it also did not help. We've run the refresh function in windows 8 and tried updating the store app. Nothing helps. HP is telling us to reset the system which will mess up a lot of programming work, most or all of our data is stored in carbonite. Any ideas to fix this will be greatly appreciated.
