Ballmer believes that one way Microsoft can bump up Windows sales is to tighten the screws on pirates. "Piracy reduction can be a source of Windows revenue growth, and I think we'll make some piracy improvements this year."
Would making WGA more restrictive than it already is do anything to improve sales? It seems far fetched in the least and simply ridiculous at the worst. A pirate isn't phased by lack of updates to begin with. The only steps I can see them taking now is making a system disable itself if it attempts to update. If that happened, odds are it'd be cracked. Wishful thinking for sure.
