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.

 

Black Screen after Log on

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable
