Microsoft has confirmed that its OneCare software changes the Automatic Updates function so that the important downloads will download automatically to their users.

“When you first install Windows Live OneCare, setup informs you that if you choose to proceed, your computer settings will be changed to automatically download and install important updates from Microsoft Update,” according to a blog entry by a OneCare team member.

“This behavior is by design and is not unique to the latest version of OneCare It helps ensure that your computer continues to receive important updates as soon as possible after they are released,” it added.
