Windows 10: Moving to a new account on same laptop

I'm getting divorced and share a Microsoft account with my ex. I want to make sure that we have secure networks. How do I move my laptop Windows 10 to a new account which cannot be accessed by my ex?

Moved to 2004; Microsoft and Office accounts are goofed up

And when I uninstalled it yesterday, it was 2.0 that day too. Having never heard of TPM until this debacle began, I don't know what version I'd had, pre-2004.

- - - Updated - - -

Okay, everything looked good yesterday, but today, back to the same old stuff.

I deliberately waited about two minutes after signing in to my PC (it's an HP laptop, HP ProBook 450 G5 15.6" LCD Notebook - Intel Core i5 (8th Gen) i5-8250U Quad-core (4 Core) 1.60 GHz - 8 GB DDR4 SDRAM - 256 GB SSD). About 75 seconds in, the Microsoft account problem, and invitation to fix, popped up:





When I did that - going from memory; didn't document as well today - I got the "work or school" account warning:





Logged into that, and then the same thing that popped up on top of my Excel yesterday popped onto the screen, although this time I'd not started anything - no Office, no Browser. Just in Windows, on my desktop, with no software running that I'd started.





So I took care of that via this (unchecking the allow to manage my device box):





And then everything was right. Probably took less than two minutes to bull through.

But this is a silly exercise to perform each morning, when it was working right just a week ago.

Could my TPM somehow be messed up?

I read https://support.hp.com/us-en/document/c05792935 and How To Easily Update TPM 1.2 to 2.0 using HP TPM Configuration Utility (note that I already have TPM 2.0, and likely had it when the laptop was new).

Here's the TPM information from device security:





Maybe I'm barking in the wrong direction, but:

1. If TPM adjustment/tweaking is the way to go, what would be the suggested steps? Remember, I already removed TPM via device manager, and had it reinstalled on restart.
2. If the problem is not TPM, then what step-by-step might be recommended?
