Windows 10: Faily Settings Seem to be preventing me from adding a new user

This is really stupid, But I cannot add a specific (Microsoft account based) user to any of my PC`s.

This is my kids account, she was setup in my Microsoft family, I have now removed her as I`m sure I had this issue before, and had to remove her as a workaround to get the account added to a new machine.

I have tried, control panel and modern settings to add the user, and neither works.

In modern settings, when I add her outlook.com account I get the error "We cant add a user to the device at this time. Its probably our fault. Please try again"

If I try to add a local user and then associate it with the same outlook.com account, I get the error "[email address] is here already - Another user on this device used this Microsoft account, so you cant add it here"

Could someone please guide me to sort this out? Thanks!

:)

 

UAC is preventing me from updating & adding new apps

I want to restate my problem. I'm being blocked from anything that requires updating and adding new apps by the User Account Control prompt. It's been suggested that I custom reinstall, but that too requires admin permission. In addition, the UAC prompt
only has one option and that is 'NO'.

It's been suggested to me that I go into Safe Mode to see if that will get around the admin permission. I kind of doubt that will work and want to know if that is a recommended procedure?

The overall question remains how do I reinstall because after I've downloaded the MediaCreationTool.exe I'm still prevented from going further by the UAC?

I have Windows 10 Home and no one else uses my computer (I live alone).

I probably created this problem for myself by attempting to do away with the PIN entry. I know now that that is not possible on my Lenovo computer.

Hi, did you follow the procedure here in removing the account originally?
Adult Account - Add or Remove from Your Family in Windows 10 Windows 10 User Accounts Tutorials

 

Yes, that's what I have done.

Still no understanding at all why I cannot add this child account to the machine.

These issues are being experiences across more than one W10 PC, so this isn't a client specific issue.

EDIT:: This issue was down to the way I have my profiles setup.

I run standard accounts for all my Microsoft account users, and a local admin account for maintenance.

This setup doesn't support the addition of family members, as the admin which is adding the family member to the machine must have a Microsoft account from the family group associated with it.
