Well I did say that I would certainly call what they did "underhanded".
I still think it's a bad idea to auto-update most software. It makes it very hard for us folks who DO know computers well to fix the PC's of users who have no idea what software changes were made immediately prior to their system needing to be fixed. Especially because these same people are more than familiar with running Disk cleanup thoroughly, deleting all system restore points, becaues they dont' have hard drives big enough for all the crap on them..
