Workarounds to try:

Low-loss solution: Add an administrator account, delete the original administrator account, most of the desktop shortcuts are lost, and reconfigure the desktop shortcuts for the application.

Steps for the second solution:

Enter the user management interface: Command mode to quickly enter: press Ctrl+Alt+Del or Ctrl+Shift+ESC to enter the task manager, click "File" - >Run New Task", enter the command or control userpasswords, and the "User Account" management interface will pop up;

Add a new user, change to an administrator type, log in to a new user, solve the problem: select other account management, click "Add new user in computer settings", add the local account, and then "Update account type" of the newly added account to be an administrator. Then log out or disconnect the account with the current black screen, log in with the new account, and the black screen will no longer appear, but the desktop shortcut of some software is lost, you need to find the path of the installation file and resend the shortcut to the desktop.

Select other account management, click "Add new user in computer settings", add the local account, and then add the newly added account "Update Account Type" to administrator. Then log out or disconnect the account with the current black screen, log in with the new account, and the black screen will no longer appear, but the desktop shortcut of some software is lost, you need to find the path of the installation file and resend the shortcut to the desktop.

As described in the smooth situation, when adding a new user in the PC settings, the "No Registration Class" window pops up and the new user cannot be added. In this case, you only need to enter the command control userpasswords2 in the new task in Task Manager (only add a 2 after the similar command in 1) to pop up the "User Account" interface. At this time, you can add and delete users and modify the account type (Attributes-> group members).

Logging in to the new administrator account at this point resolves the black screen issue.
