Almost all of the software products of Adobe like Adobe Reader, Acrobat etc gets installed with a small tool called Adobe Updater which keeps getting invoked often, trying to connect to internet to check for updates for the installed Adobe products.
Most users probably do not mind the regular automatic update checks but some might prefer to update the Adobe software products manually. This is important in business environments where patches are extensively tested before applied to client machines.
But if you are someone like me who find it unnecessary and irritating, all that you need to do to disable automatic update checks is to execute the Adobe_Updater.exe which is located in ../Program Files/Common Files/Adobe/Updater6 folder. The application will perform an update check and notify about the available updates.
A click on Preferences will load the configuration screen shown in the above screenshot. Unchecking the “Automatically check for Adobe updates” box will do the trick. Mac OSX users can basically do the same. The location of the Adobe Updater program on their system is /Applications/Utilities/Adobe Utilities/Adobe Updater5/.
