My pc is an HP envy 17 notebook pc, running Windows 10 Home, version 1607, build 14393.576, with 16 GB ram, 64-bit OS.
All startup apps are disabled (under System Configuration Services and Task Manager Startup), except for the Microsoft services.
The problem is this:
When I turn my computer on I can see the HP logo with dots circling.
When lock screen shows up with background pic and time and date, I press enter key to go to login screen.
The login screen is set up with a different background color, and it opens with no password prompt. After about 30 sec it returns to the lock screen.
After waiting about 5 minutes, I can press the enter key, and the login screen opens with a password prompt. I have tried waiting less that 5 minutes at the lock screen to return to the login screen, but there is no password prompt until 5 minutes have passed.
After entering the password, the computer behaves normally.
I ran Windows Repair (3.9.12), but the login delay was not fixed.
