Have any users - who use Photo Gallery (part of Windows Essentials 2012), preferably on Win 7 - upgraded to Win 10?    Have you checked out whether Photo Gallery, including all the tags you've attached to your media, continues to operate seamlessly on your machine after the Win 10 Upgrade.   Any problems at all?

How about Movie Maker?   I note Microsoft provides contradictory information about compatibility of Movie Maker and Window 10 - see the following:

1) They are NOT compatible according to:

2) They ARE compatible according to:

What can a user do but ask other for their real world experience!
