You can use the assoc command to associate an application to a file type for all users. You'll need to put the server into install mode before running I think it will be 'assoc .gif=iexplore' Andy ----- Original Message ---- From: "Minero, Hector B CIV NSWCDD, K55" <hector.minero@xxxxxxxx> To: thin@xxxxxxxxxxxxx Sent: Thursday, October 11, 2007 1:36:13 PM Subject: [THIN] Re: File Associations Thank you all for the responses.

You have per-user file associations that can be defined under HKCU\Software\Classes, and of course you've got windows file associations, under HKCU\Software\Microsoft\Windows\CurrentVersion\Extensions and Windows explorer doing it's own things with file extensions under HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts. And that's not covereing mime type definitions Per-user file asociations override per-machine ones, and the windows and explorer settings override the stuff under HKCU\Software\Classes so anarchy rules. It'd almost make you think that the operating system, windows and windows explorer developers were all doing their own thing, but I'm sure Microsoft would have things better integrated than that ;-) Seriously, if you want to totally control what applications open a particular type of file, you're going to have to manage the per-user stuff as well as the machine settings. It's not that hard to do. regards, Rick -- Ulrich Mack www.commander.com On 10/11/07, Minero, Hector B CIV NSWCDD, K55 <hector.minero@xxxxxxxx> wrote: Hi all, I am trying to associate *.gif files with Internet Explorer for all users. If I modify giffile entry in the HKCR registry,it does not apply to all users. How am I suppose to make this a global change. Change user /install and change the file assoc. in Windows Explorer?
