I have to configure a bunch of computers with Windows XP and im trying to create a script with Autoit so make my work easier. The issue is the following:

I want to make certain extensions to open with a determinate software FOR ALL USERS in the system. (For example, open all .PSD files with XnView). I figure the best way to do this is to manipulate the register, but Im not sure how to do this task.

Can someone please how to achieve this goal?

Thanks a bunch

if you have peer-to-peer LAN it is impossible by GPO. You should have Windows Server at LAN and Active Directory. – Alexander Pavluchenko Jul 19 '11 at 10:20
