Ahh, Ok. You posted your problem in this forum which is for Windows 8 Help and Support.
Part of the problem is that Microsoft made several changes to Windows Essentials and completely removed some apps from W10, such as WLM (Windows Live Mail), which was the MS native Mail app for 5 years. I don't know about the other apps, specifically WMM (Windows Movie Maker), as I used to teach that program in my Computer Media classes I used to teach several years ago. Í haven't attempted to run WMM on W10, which requires you to download from the Microsoft Apps Store *and you need a Microsoft Account Login on your W10 in order to access the store*.
In any case, here's a good video I found that explains how to find it:
I can't be certain whether it's exactly the same WMM as contained in the 2012 Windows Essentials you have, but this video has the link to right place on the Microsoft site where the WMM that's compatible with W10 lives. Give it a try and let us know how it works for you!
Best,

NOTE TO KEMICAL: Hi Ross, the OP here posted into the wrong sub-forum; if you get time, can you please move this over to the W10 Help and Support sub-forum? Thanks--BBJ.
