I just updated to Windows 8.1 from Windows 8, everything was working fine at the beginning, but later Windows Metro Apps suddenly started crashing, later Black (X) appeared and some apps renamed to weird names after attempt fixing the problem, PC Settings worked, and Windows store worked, before the fix it wasn't, but other apps did not work and kept crashing.
Next problem, the open with dialog started not to work properly, if I right-click Open With> Paint example, it would work, but if I choose open with "Choose a default program...", it will work properly, but if I click More options and then "Look for another app on this PC" then I choose an executable file and click Done then nothing is going to happen, if I am going to run the program it will run the other program it was set to even when I set "Use this app for all .png files.
The third problem, I went to the Devices and Printers control panel, when I click "Add a printer" it tells me "Windows can't open Add Printer." "There are no more endpoints available from the endpoint mapper"
., Add a device still works.
The forth problem, computer start time went too slow suddenly, like black screen shows before the start screen and after logging in that is causing delay, not sure what is the problem.
I am sure there are some other little and big problems too, I still feel the system unstable.
