How to stop being logged out of everything automatically when I turn off my laptop

SOLUTION

For anyone who hasn't seen in the previous replies, the solution is to download Firefox and use that as your main browser! Someone on here worked out that the problem is actually with Google's software, not with Microsoft. Chrome, Edge and Opera all use software from Google, whereas Firefox doesn't. I stopped using edge a few days ago and started using Firefox, and I haven't had a single problem since!

I'm having the same problem on a desktop that I never shutdown.  It is set to go to sleep after two hours, but that doesn't cause this problem (and it has nothing to do with my settings or clearing cookies--all that is set properly).  I go to my Yahoo, Microsoft, and Google emails accounts, open Photoshop for a little while then come back to being logged out of all my emails.  It logs me out of Amazon also, but not other websites where I am logged in.  I use Firefox and minimize my browser instead of closing it (unless it seems fussy which usually indicates there is an update).  The logging out is completely random and doesn't have anything to do with what I'm actually doing on my computer.  I was so excited when the update came, and I briefly thought that the problem had been fixed, but it wasn't.  It's as bad as ever still.

BTW I have exactly the same problem as stated up above, but I get logged out from everything after a while no matter what; I don't have to shut down or even shut the lid.

I have seen that on my PC, but rarely (lost logins, no reboot). Some thoughts: Most browsers have options to delete cookies on closing the browser. This is generally includes but is not limited to "private browsing." If you can rule out browser options, then you might look at your security software to see if it is set to do anything relevant to this problem. I don't think that is very likely, however. If this is happening a lot, it might be due to a problem in updating software likely from Google or Microsoft, where for some reason the updating fails to complete, so it tries to do it over and over. This is if the updating deletes all cookies, as Google Chrome Elevation Service seems to do. If you have corrupted updating software, there may be relevant messages in the Windows log files, accessible through the Event Viewer (note: this takes you to a very geeky place, I don't understand most of what I see in it).

At the moment, things on my PC seem to be stable, even using sleep mode. I may try deleting Chrome, then reboot and do a fresh install, depending on how things go. If you are using Chrome, you might try this.

To get a truer handle on login deletions, note that some sites (financial, especially) will automatically log you off after a relatively short period of inactivity. I used YouTube and Yahoo Finance in my testing because they don't seem to  do that. If my logins for them are unexpectedly deleted, I know something unusual is happening.

There may be multiple possibilities for what is causing the problem on your machine. If you're not deep into how Windows works (diving into the registry, group policy editor, etc.), you might try using Firefox as your primary browser until someone can sort all this out. If you are already using Firefox and have the problem, that would be interesting to know. Firefox at least lets you know when it is being updated.

I did try hopping on one foot and facing North, but nothing. I'm going to try the other directions now! :D
