Windows 10: Why does Windows 10 always sign me out of Microsoft, Google, and Slack during restart?

I recently bought a new PC a Dell Vostro with a fresh Windows install, and I have it updated to KB4576478/Version 2004. It has an odd behavior that I cannot figure out how to stop. Every time I restart the computer or it restarts itself after an update, I have to log back into everything.


I've been logged out of every Office 365, OneDrive, and Edge, and I've also been logged out of all of my Google Products File Stream, Gmail, etc. as well as my Slack desktop app. The only thing that doesn't get logged out is my VPN, which is just weird.


This didn't happen on the PC that I was using until a month ago which was updated regularly, and nor did it happen on my work PC, which my job has clamped down under all sorts of security.


I assume it was some security setting, but I can't find anything in the various forums. It might be out there, but the words to describe this behavior are very general so it's really hard to parse the search results.


Anyway, any help would be appreciated.

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”

Microsoft Selects Dolby Audio for Windows 10

it would've been great if microsoft added HEVC decoders, LAV filters along with other codecs with Windows 10, and developing WMP to be better than VLC, KMPlayer and such sorts of media players.

Nevertheless, this is good step for microsoft, by far.

 

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.
