Guys, if you have finished the upgrade but only get a black screen of death with a white cursor AFTER LOGGING IN and even safe mode won't help, then there is a way to restore!
You have to, from the lock screen or Ctrl Alt Del screen, click the Power menu, hold SHIFT and click restart.
This will open up the blue menu. Go to advanced settings, > advanced start up settings.
Then the computer will reboot with a blue menu like this: http://www.eightforums.com/attachmen...p_settings.jpg
You have to press F10 for more options, then "1" for recovery options.
Then the PC will reboot into the same original blue menu, but this time with more options. There is a small option at the bottom that says "more settings" and then on there you can click "Revert to previous build".
This took about 5 minutes and I was back in Windows 8.1 still asking me to upgrade again.
I hope this helps!

Thanks to every one who posted. You helped me refine my search to get to a fix that worked for me.
IF YOU ARE STUCK AT THE BLACK SCREEN AND CURSOR:
This fix worked for me.
If you are at the black screen and cursor, then Microsoft says you may be at your boot signon screen but are unable to view the screen. The sign on is still there. So here is their fix:
1. Push the control key. (This moves the focus to the password box)
2. Enter your logon password and push <Enter>. (When I did this the cursor vanished.)
NOW WAIT. It took my relatively fast Alien computer about 5 minutes to finish the set up and (SMILE) there was Windows 10.
NOTE: If you have been pushing on the keyboard, you may need to reboot to get to a clean log on page to perform the above log on in the dark.
Hello i have windows 7 and i am updating it, it was around 54 percen and it re booted, then black screen with no cursor for 2hours and nothing.
What should I do?
I read somewhere to try an HDMI cable instead of the normal monitor cable, so I connected my PC to my TV and was able to finish the install. The monitor was unable to display the picture so the install must have changed the graphic settings. Once the install was finished the monitor worked again, although it had changed to a multi monitor set up.
I have been having the same problem on my laptop since I installed windows 8. They never fixed the junk in windows 10. The whole lock/login screen is a POS and needs to be removed.
anyway, rant finished.....
If you have this problem one way to get around it is to wait until your hard drive light stops so you know it's booted up then press your power button and let go of it, just a quick click(this only works if you haven't changed the settings) to put your pc in sleep mode. Wait a few seconds till your hard drive light stops and click it again. When it comes back it will boot up the graphics and your display should work. I had to do that every time I changed any settings. Now I have to do it every time I boot windows since I changed the settings to get rid of the lock screen and automatically log in to windows without using a password.
When you install windows 10 for some reason it sets your GPU display to duel monitors so when it does its last warm reboot that brings you to the log in screen your display isn't set to default primary display hence the blank screen if you reboot again press F2 or what ever key to enter bios disable duel monitors setting under GPU then save and exist and windows 10 login screen is there.
