Win 7, GPEdit, Registry hack?

I'm sure this is probably a simple question to you all but I am not very experienced in regards to this particular need and humbly hope someone can point me in the right direction.

I'm using Windows 7 Enterprise 64-bit. I need to run a *.vbs file from a network share at start up. I've added a registry entry to run the VBS file from the network share at start up. At first I would get prompted with the "Open File - Security Warning" message. So I went into GPEDIT.MSC and I made the change in "User Configuration\Administrative Templates\Windows Components\Attachment Manager\", open "Inclusion list for low file types", enabled it and added the ".vbs" entry and applied it. This works fine and does what I need.

Now what I need to do is apply this across multiple computer systems. Unfortunately the location does not use AD yet and this is all across local machines. What I need to know is, is it possible to make these Group Policy changes in the Windows 7 registry so that I can export the registry changes and then apply them via a script to multiple computer systems? I've tried searching Google but while there seems to be reference to the registry entries for XP I can't seem to find anything for 7.

Thank you in advance.
