Windows 10: Windows 10 lock/sign in screen blury since upgrade to 1903

All 4 of my Windows 10 computers have been just upgraded to version 1903. Since the upgrade all 4 show a blurry background image on the lock/sign in screen. Is this a bug?

:)

 

different lock screen and sign in screen?

Step 2b is labeled as Change the Login Screen Image, but the steps show you how to change the Lock Screen image. Step 2a is irrelevant. It only tells you how to change the desktop background.

What I want to do:
Set Spotlight as the LOCK Screen Image(s) - Done
Set the Win 10 Hero Image as the SIGN IN Screen Image - This is the one that shows after you click on the lock screen and you are able to type your password. If I uncheck "Show Lock Screen Image on Sign In Screen", it shows a solid blue background behind my Password box and user image. This is what I want to change to the Hero Image....

 

Windows 10 spotlight lock screen wallpaper is not present in sign in screen. Plz. Let me know the remedy

Hi,

It's possible that the option to show a background picture on your sign-in screen is disabled that's why
Windows Spotlight is not showing there. To provide the best solution to the issue, we'd like to isolate it first by asking a few questions:

• Were there any changes made on your computer settings prior to this issue?
• What are the troubleshooting steps that you've tried so far?
• Which Windows 10 version and build is currently installed on your computer? To check, click the
  Start > Settings > System >
  About.
  

Meanwhile, we suggest that you perform the steps below to enable the background picture on your sign-in screen:

• Click Start > Settings.
• Go to Personalization > Lock Screen.
• Enable the option under Show lock screen background picture on the sign-in screen.

We look forward to your response.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.
