You have to stop "C:\Program Files\Common Files\Adobe\Updater5\AdobeUpdater.exe" from running. Deletion won't help as adobe will create a new folder and file. Here is how it works:
- First, start your task manager and kill the "AdobeUpdater.exe" process.
Right click the new file "AdobeUpdater.exe", select "Properties", then "Security".
Mark at "Group or user names" "System", press "Edit" and click on all "Deny" checkboxes.
- Now do this for all users "Administrator" etc. and press ok.
All done. Adobe will never again be able to update. You can test it by trying to start the update within Adobe Acrobat manually. You will see, that
nothing will happen.
