What should I do if the user name of the task manager is null?

Sometimes open the task manager and find that the column "User Name" is empty. The normal status is to display system or the user name currently logged on.ProgramIs it started by the user or the system.

 

Solution:

In the running process, enter services. MSC. This is the Windows command to open the Service Management window. Find the terminal service, double-click the corresponding Properties dialog box, change the startup mode to automatic, and start the service.

Then re-open the task manager to view the normal user name.
