I used to have Windows 7, and windows live movie maker  worked great. I upgraded to windows 10, and my videos open up, but wont PLAY. 

 I understand enough about computers to do installations and downloads, but not too advanced… A friend said I might need to go into administrator mode  and install windows essentials again , but I don't know what that means. 

I also researched an article which said I need to download Windows movie maker 12. 

 Thx! Your help is appreciated :-)
