Strange message about Trados TMAnonymizer during start of Studio 2021

This is the message which strangely does NOT appear on the screen until I activate it from the task bar. (This means that it can hold up the opening of Studio until I remember to activate it.)

What does "Update the list of 'Useful Tips'" mean? Opening the list does not help; this message still appears the next time I open Studio.

And the message from User Account Control has yet to appear.

What should I do?
