i MonH, Unless someone deleted the file, it should exist on your system. If you're on a 32-bit OS, the file will be in C:\Windows\System32\Macromed\Flash. If you're on a 64-bit OS, the file will be in C:\Windows\SysWOW64\Macromed\Flash. You can edit the file manually, or edit the update settings in the Flash Player Settings Manager, which may be easier. To launch the Settings Manager, either navigate to the Control Panel and select the Flash Player icon, or launch a non-Chrome browser and view Flash content, then right-click on the content to display the Flash Player context menu. Select Global Settings. When the Settings Manager displays, navigate to the Advanced tab. Click the Change Update Settings button Select the Never check for updates (not recommended) radio button Your update option has been set Viewing the mms.cfg file after making the updates, it should contain the following: AutoUpdateDisable=1 SilentAutoUpdateEnable=0 AutoUpdateDisable=1 is what disables the updates (background and notification) completely. Note that whenever you uninstall Flash Player the update settings are reset to the default setting (AutoUpdateDisable=0). You'll need to be sure to select Never check for updates (not recommended) when you install Flash Player again. -- Maria
