If I try to search for stuff using the start menu, nothing happens. The mouse will flicker with the spinner. If I turn on the search box, typing in it will cause it to immediately reject what I typed and go unfocused.
I got this error when I started my computer: Windows cannot access the specified device, path or file. I tried to go to the path it specified, but was rejected for not having permissions. I tried to run the app with command prompt and got this error: Access is denied. At one point yesterday it started working again, but after a restart, it has stopped once more.
I just did a repair to try and fix this, which fixed another issue I was having but left the start menu unchanged.
