The Windows File Explorer has stopped working! Yesterday it was working, today it is not. The symptom is that when I click on the File Explorer icon in the taskbar, nothing happens. The result is the same when I click on the File Explorer icon in the start menu. The day before it stopped working, Windows halted with the following message:
STOP CODE: SYSTEM THREAD EXCEPTION NOT HANDLED
I don't know whether the two are related. So far, I haven't detected problems with any other application.
