Add network support to Windows Live Movie Maker - Windows 7
You use Windows Live Movie Maker to edit your movies. Now you've probably noticed that it does not allow you to import videos from a network location. A problem you can solve easily by making a small change in the registry.
When you open a video file from a network, Windows Live Movie Maker lets you know that this is not possible.
To correct this, click Start. Enter the command regedit and confirm with Enter.
Then pull down the key HKEY_CURRENT_USER, Software, Microsoft, Windows Live, Movie Maker.
Click menu Edit, New, DWORD Value 32-bit.
Name the value AllowNetworkFiles and double click it.
Set its value to 1. Click OK and close the Registry Editor.
You can now import video from your network shares.
