As well as what gaiusg99716536 has posted we do the following in our environment. Using a batch file for the install add the following line: SCHTASKS /Delete /TN "Adobe Flash Player Updater" /F This will remove the actual scheduled task in Windows that runs the auto updater service for Flash. This will stop any kind of updating checks for Adobe Flash. You can double check that this task already exists using task scheduler in Windows. We also copy the mms.cfg to the following locations on our x64 systems: C:\WINDOWS\System32\Macromed\Flash C:\WINDOWS\SYSWOW64\Macromed\Flash Hope this helps.
