Well we can argue wether a knife is pro or con user when Microsoft stabs said user in the back with it. Microsoft would say that it provides a secure (tm) resting place for the users hat and is not only very pro-user in doing so but also important for the continous operation of said hat. My point is just that, Microsoft used Windows Update to push unwanted software in the past and as such Windows Update was never entirely a pro-user software, something always undermined by Microsofts willingness to put its own goals above its users needs.
