Black screen after login


This thread lead me to a very simple fix for exactly the same Black Screen After Login problem, but I have a different fix (it took a few hours to solve it though!).

I think it's best to do this from another Administrator account.
If you do not have another Administrator account then this is how to create one (I have copied and modified this bit from Black screen after upgrading to Windows 10 - Microsoft Community ):

1. Ctrl+Alt+Del, select Task Manager, File->Run new task... Open: cmd.exe then check the "Create this task with administrator privileges" then click OK.
2. In the Command Prompt window, type the following commands (changing “<password>” to something of your choice):
   net user test <password> /add
   net localgroup Administrators test /add
3. Reboot the PC

To fix the Black Screen After Login problem, from another Administrator account, just delete all the files in the following directory:C:\Users\<BlackScreenUser>\AppData\Local\Microsoft\Windows\Caches\
Obviously replacing <BlackScreenUser> with the user account that has the issue.
