During their Windows 10 blitz, some blockhead at Microsoft thought it would be a great idea to push out "nag" marketing messages to Windows 7 users, under the guise of Windows Updates. To make matters worse, it took them a few tries to get it right, resulting in several related patches which might be shown.
When I install new Windows 7 SP1 computers from scratch (and yes, there are still legitimate reasons for doing so), what's the quickest and easiest way to prevent these unwanted "updates" from ever getting applied in the first place?
