   The colonization of everyday life
   "...a clause was smuggled into a security patch in June.
   On the other hand, users already consent to similar conditions whenever
   they use the Windows Update facility - and few complain.
   The change needn't apply to corporate users. Microsoft recently
   introduced Software Update Services, which allows managed upgrades
   across the Intranet to users with Active Directory. (So you don't have
   thousands of desktops hitting Microsoft servers at once).
   We've asked Microsoft if this was a legal or a technical decision, and
   what was behind the decision to make installation of the service packs
   conditional on this clause. We await their reply.
