I have no idea how they went missing. I just recently upgraded from Windows 8.1 and all tiles were there well almost all. Now after playing around some and sorted them again most are now gone for no apparent reason. I did delete the windows.old folder but i suppose it was safe to delete?
Strangest thing still almost all my installed programs have vanished from the program list, they are not showing at all and the Store tile doesn't work either.
I am desperate please help me!
