I think Windows 10 on my PC might have just updated. Now I get stuck at the login screen. When I press the windows key or click on the screen, the mouse pointer shows a busy blue circle spinning icon and the screen goes black, then goes back to the login screen. The input box for password never shows. It does this everytime I press the windows key or click on the screen with my mouse. It is an older, low power pc.
What should I do?
