Windows 10: Windows 10 takes over 5 minutes to reach the login screen

Windows 10 takes over 5 minutes to reach the login screen
How can I speed it up?
I'm using Windows 10 20H2

I have already done chkdsk, dism and sfc and no errors were found. I've also installed windows updates.

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)

One more thing to be considered; black screen 5 minutes after signing in only occurs with my admin sign in account; my wife signs in in a split second with her non admin account. So admin sign in account should be limited to solve this.
