what happened to windows movie maker?! how to make music videos part 1

if your a rapper like me you know this program was free. if your a youtuber like me it was the go to program back in the day. i had to buy a program called videopad which was around 15 to 30 dollars at the time just to get a program that can help me make videos but im sure theres other free video making programs. windows movie maker was discontinued for pc i think sometime after windows vista. i still have a movie maker pc but that computers old. i just wanted to document something because i made a cool music video with movie maker. and this was a video where the lyrics synced up because i had the music playing in the background while the camera was recording. so you just had to say the lyrics at the same time as the recording. and then line the mp4 file up with the song in movie maker then turn down the mp4 after its synced. ill have a more in depth music video tutorial in the future but this is it for the most part. im unsure how much it will help.
