For the layman.....Window Movie Maker is enough for basic home editing because it doesnt require any special courses. You can just click it and figure out yourselves. But if you wanna do some thing creative, then go with the Adobe Premier. It is THE BEST editing software around. Its a professonal editing software but if you are really interested then you can figureout the basic things. You can also go to youtube and watch the tutorials regarding this software. I can not think of any other editing softwares besides these two right now.

Good Luck!!
