trouble with windows movie maker

Hello, I use windows movie maker quiet a bit, but the other day i went to go use it from my desktop ( I cant recall word for word what it had said) but it was along the lines of programs has been changed or moved. So as i double clicked it has just asked to get rid of shortcut, well me knowing I can easily just find and remake a shortcut I had accept it to be deleted. Well a few moments later I went to go find the program itself and cannot find it. I dont have a file for it anywhere on my pc, i searched manually for it and ive also typed it in search bar. I tried to re-install the entire program but it says I have all essentials. I am completely lost and have know idea what to do to fix this problem. I upload videos on a regular basis but have yet to even try since ive discovered this problem. Please help me, thank you.
