Windows 10: windows 10 freezes after startup

Windows 10 Pro running on Dell 5810 desktop, as upgrade from windows 7 64B. Win vers.1909, build 18363.778
The problem:
At startup, after regular boot and UAC completion I get a regular window with Fences correctly run and several start apps regularly run. But missing Outlook 2016 run and I suspect that this is the reason for the problem.
What I get is a mouse pointer that becomes a circling ring when I point to the lower bar.
To unlock I have to click on windows key or force any of the icon in the lower bar. The screen becomes black for 2 seconds and then the system becomes unlocked.
At this point I must manually run Outlook 2016, despite it is included in the start apps.
I did hundreds of attempts to solve the failure and googled for hours. Windows automatic repairs, reinstallations of Outlook, editing of Start Apps, editing of registry "run" . I have not reinstalled windows 10 as I would like to avoid apps reinstallation. Pls give some hint. Thanks

:)

 

Can't get GPU-Z to start with Windows 8.1 startup

I'm not sure how to do that. Could you list the steps for a noob?

 

Windows 10 freezes randomly

I had already tried turning off fast startup, to no avail.
Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin

I had tried that as well... no result.

 

Windows 10 freezing at log in

Hello Frank,

A failed update or one-time startup process can sometimes cause stopping, freezing, or reboot-loop issues during the login process. To isolate the issue, we suggest that you answer the following questions:

• Do you have a USB device attached? If yes, can you remove the device and log in again.
  
• Have you tried turning off the WiFi feature in your laptop before logging in?
  
• How about running a Startup Repair in your Windows 10 laptop? (Boot to Advanced Startup Options>Click on Troubleshoot> Click on Advanced options> Click on Startup Repair)
• Aside from the above steps, what other troubleshooting steps have you done so far?
  

Looking forward to your response.
