MICROSOFT SOFTWARE LICENSE TERMS
Software updates you receive through Microsoft Update are governed by any license terms that come with them. If no license terms come with them, they may be governed by the original license agreement for the software that they update. You should check that license agreement for details. If you choose to receive updates automatically, you won't receive this notice again or be notified of which products are being updated, but you can review your update history at any time by going to Windows Update in Control Panel.
