I recently realized that Adobe Photoshop CS3 and Adobe Premiere CS3 were updating themselves without permission to do so. I looked for an option within each respective application to disallow automatic updates, but could not find one. After doing some searching, I found this workaround.
To disable automatic updates in Adobe CS3 for Windows Vista (Should work for Windows XP too):
1. Start > Run > C:Program FilesCommon FilesAdobeUpdater5AdobeUpdater.exe (if this does not work, navigate to to the common files folder and follow the same directory structure to get to AdobeUpdater.exe.
2. Adobe Updater will open, and select continue as it searches for updates.
3. On the screen where you tell it to download the updates, it will have a preferences link. Click the preferences link.
4. Un-check the box that says “Automatically check for updates.” and hit okay, then close out of the updater.
