Microsoft's arrogance will be their undoing. Businesses will start to take serious looks at alternative products if Microsoft's "forced update" system continues to cost users and businesses time and money.
It is very difficult it is to explain to small businesses that the Microsoft update service screwed your computer, pay me to fix it and you have no recourse but to sit there and wait for it to happen again. (and don't try to tell me to use a WSUS server, we are talking about places with 10 users or less and in some cases, don't even use a window server.)
