Remember how we told you that Windows Vista was getting extended support? Well here's a little PSA: that new phase begins tomorrow, and it's slightly different to what Redmond calls 'mainstream' support. You'll still get security updates until April 2017, but according to Microsoft's general support policy you'll lose certain other benefits. Key among those are warranty claims and no-charge incident support. So, after the party is the after-party -- at least until you're ready for an upgrade party.
