Hi, for any newbie I would definitely recommend this cool iMovie download for Windows 10 I respect the most. There are a lot of applications for video editing, you need to choose the one that best suits your needs. I personally prefer to use imovie for windows it is a free video editor application, very easy to use and effective.
Sorry Imovie does not exist on windows, it was created by apple for mac os only.
You can go with the windows alternatives but other than that you may just have to buy a mac.
