TO ALL WHO HAVE HANGING "Initializing installation"

I had the same problem. I also couldnt get my folder properties to show. I
found a temporary fix.

Press control + alt + delete, click on the processes tab at the top, find
inetinfo.exe, select it, and at the bottom right click end process.

I don't know why, all I know is that it works.
