The Start menu and Cortana are not working as shown in the following figure. The next time you log in, we'll try the wrong hint.
Solutions
Method One:
If the "This computer" icon is on your desktop
1, in the "This computer" icon on the right click, select "Service";
2, in the service window left-click User Manager service;
3, in the pop-up window will be the startup type selected as "Automatic";
4, click on the screen in the middle of "Log off immediately", or press Ctrl+alt+del to select logout or restart.
Method Two:
If the "This computer" icon is not on the desktop
1, press Ctrl+alt+del to open the Task manager;
2, click the "Services" tab, select a service in the tab, press the right button to select "Open Service" (if the Task Manager does not have a service tab, click the lower left corner of the "Detailed information" button);
3, in the service window left-click User Manager service;
4, in the pop-up window will be the startup type selected as "Automatic";
5, click on the screen in the middle of "Log off immediately", or press Ctrl+alt+del to select logout or restart.
Note: There is no response after pressing the WIN+R key after this failure, so you cannot directly enter the Services.msc command to open the service directly.
