Windows 10: How can I stop the Microsoft account popup from appearing during device startup?

When my computer boots, a white loading screen as shown in the included screenshot appears. The popup cannot be closed, and no hotkeys seem to work. While Ctrl+Alt+Delete allows me to open Task Manager, I am unable to use it to close the popup. Rebooting the device does not resolve the issue either.

My Device Won't Appear On My Microsoft Account

I'm new to this page and it's because I want to download NVIDIA, but for that, I need a device on my account. The profile on my PC is connected to my account on Microsoft, I've checked on this very PC and even my phone the page of devices on Microsoft, I've
followed every single step correctly but my PC just won't appear in the list of devices on my account, what can I do?

Hello Flemmingk,

Could these other devices be from friends that you may have signed in to your Microsoft account on for something?

Either way, you can remove these devices.

Afterwards to be safe, I would recommend to change the password of your Microsoft account, and enable two-step verification if you haven't already.

Unknown devices on my Microsoft account

Thanks Brink
I get different reactions every time I try to delete a device, but the result is that I cannot remove the devices.
I'll go back to local accounts and delete the Microsoft account.
I changed to Microsoft account because I wanted to use the Continue on PC feature. This feature doesn't work so I think that I'll just forget about it.
Thanks for your interest.
