Windows 10 black screen for login screen

[Deathrattle]

After upgrading to windows 10 I receive a black screen for the login. There are no visible controls. There is no visible cursor or mouse pointer. However everything does appear to be working, except the display.

When I hit [enter] - password it will briefly show me the login screen and login to the OS giving me full screen access and everything else works fine after I login (ie the display works and the computer behaves properly with no display issues).

This issue only impacts the display of the login screen and the issue started immediately after the Windows 10 anniversary update.

I have updated all device drivers (including but not limited too the Display drivers).

some high level system info.

Issue resolved.
I ended up downloading DriverAssist as recommended by the following article

I did not reinstall the graphics card but I had a few other old drivers and once they were updated the issue was resolved.
