I like iTunes 10, so I keep an installer around.
Unfortunately, iTunes has lately taken to updating itself to version 11 without even asking anymore, meaning every couple of days I start it up to find I have to uninstall it, restore the music library from backup, and re-install version 10.
I have uninstalled Apple Software Update, as well as denying this and iTunes access to the internet with my firewall.
Yet, it still manages to update.
What executable is responsible for updating iTunes on Windows?
