1) System Preferences > App Store > Disable 'Automatically Check for New Updates'
2) Open Terminal and enter the following command to enable the Debug Menu in the App store. Triple click it, copy it, and paste it into your prompt:
defaults write com.apple.appstore ShowDebugMenu -bool TRUE; killall AppStore ; exit
3) Open up the App Store, from the debug menu > Clear Cookes <> Reset Application
4) From the menu bar, Store > Sign Out
5) Close the App Store and reboot
Notes:
-To disable the debug menu, change 'TRUE' to 'FALSE' and run the command
-You have your own reasons for not wanting to update these applications, that is fine. However, it is always wise to keep applications up to date...especially when they accompanying an OSX upgrade.
