After moving to a new computer, WLM worked just as it has under Win 10 for years - until I had to change my Microsoft Account login.  Since then, every time I open WLM, it demands a new sign-in, and ONLY accepts my Microsoft account login.  The pop-up says, "To help protect your Online id account you must signin again."  This can be canceled, allowing access to WLM, but is an unnecessary annoyance, as it ALWAYS comes up when I start WLM.  I ran Windows Essentials Repair, but that made no difference.  How can I get rid of this pop-up?

I know that Windows Essentials is no longer supported, but this appears to be a Windows bug.  The OS is a fresh install of the refurb edition of Win 10 ver. 1803.
