How to prevent Update Notifications?
For a long time now, we've had mms.cfg deployed to our systems to prevent the Update Notifications appearing for staff; as we manage updates via SCCM. Contents of the mms.cfg file is just "AutoUpdateDisable=1" & we have it deployed to both System32 & SysWow64 versions of the "Macromed\Flash\" folder.
Over the last maybe 6-12months, we've been receiving calls from staff who are still getting the update notifications occasionally. Checking the flash control panel applet, shows that 'never check for updates' is indeed set.
Today I've received the update notification myself, so i'm expecting some calls again today...
The popup window appears to be from the process "FlashUtil64_26_0_0_151_pepper.exe" (or maybe it was FlashUtil32_26_0_0_151_pepper.exe... didn't check, just saw pepper....).

How can we make sure this popup stops happening for our staff?
