Windows 10: Windows Startup, 20-30 second delay before login screen

Background, I just removed an NVideo card from my machine, and reverted to Intel Graphics i7-6700k cpu.After the switch I see the system boots fine, I see the Window pane graphic and the rotating circle, then the screen flashes and goes light gray for 20-30 seconds... and then the login screen appears. Before removing the NVideo card, the login window came up about a second after the Window graphic disappeared. Next I removed the NVideo drivers in case that was a problem... but no joy.I have an old i5-2600k Intel Grapics and it goes from Window pane graphic to login window in about 2 secon

Lock screen to Login Screen delay issue

I have an issue where there is a huge delay between the lock screen (the screen where you have a background and time) and the login screen (the screen with an account picture and dialog box to input the
password).

I tap/press any key/click on the lock screen and it takes so much time to load the login screen, sometimes the lock screen reappears after 10-15 seconds or so before i can tap again to try to go to the
login screen.

I've tried the following to fix the issue

• Disabled widows spotlight
• Disabled lock screen
• Performed Clean Boot
• Tried Safe Mode
• Turned off startup services
• tried sfc command

My Windows 10 version is 1903 and is fully updated as of the time of publishing this post. I have pin set up to login.

It's definitely not because of the old or slow hardware because

1. On a much older hardware the startup might be slow but this problem doesn't exist.
   
2. After once i login successfully and lock the computer (start+L), the issue's still there. That is about 30 seconds waiting time between lock screen and login screen.
   

I'm really looking forward to all your solutions.

 

5 min delay on cold start between login screen and bg screen

Ok, let the powershell command run overnight
If the command didn't solve the problem, the try these steps in order:

1. Disable superfetch service
   • Empty the following folder c:\Windows\Prefetch\
   • Restart the computer
   • Si ça ne marche pas, passer à l'étape 2;
2. Disable the AppXSvc from the registry: change the "Start" key value from 3 to 4 (see the screenshot)
