Unfortunately, there are only two version of iMovie: one for Mac OS X (iMac/Macbook) and one for iOS (iPhone/iPad). If you are a Windows user, you'd better to download an alternative to iMovie for Windows to replace iMovie.

There are numerous of tools that claim to completely do what iMovie does. For more information, visit here: iMovie for Windows.

Hope it will help you more or less.
