Windows 10: After Win 10 Pro upgrade, No Logon Screen

Win 10 Pro Dell OptiPlex 755 updated to latest version of Win 10 Pro and upon reboot, the logon screen only displays for a milli-second. Can't log on at all. Help!

WIN 10 LOGON Failure

Attempted WIN 10 upgrade to WIN7 Home Premium SP1 on 3 occasions (separate downloads), the last time with the recent WIN10 update. Downloads and installation appeared clean each time until the LOGON screen appeared. When I entered PW on LOGON screen and
selected 'Next', the process stalled. Eventually, system automatically entered reboot sequence, with the same results. I reinstalled WIN7, confirming the PW I used for the WIN10 LOGON is correct.

Any suggestions on installation issues and remedies?

 

Lock Screen to Logon Credentials not working as desired


The recent upgrade(s) of my Windows 10 Pro sees Version 1709 and OS Build 16299.19 loaded. My original settings of not seeing the lock screen picture not appearing on the logon screen has seen the lock screen picture not being displayed at all, instead it is just a plain colour. However if I allow the logon screen to appear on top of the lock screen picture, then the lock screen picture is visible. A change the picture, even to one of the defaults, it still doesn't work as desired.

Suggestions to resolve this issue welcomed.

 

Win 10 Home to Pro upgrade

How do I upgrade from Win 10 Home to Win 10 Pro with a digital Licence. The in structions say

• If you have a digital license for Windows 10 Pro, and Windows 10 Home is currently activated on your device, select
  Go to Microsoft Store and you'll be prompted to upgrade to Windows 10 Pro for free.
  

Fine, but how do I get a digital Licence for Win 10 PRo??

Going to Microsoft Store via the upgrade with digital licence link, provides no opton for upgrading.

Any solution??
