Microsoft's "patch Tuesday" went off last night, so you might've noticed that your PC had restarted whilst you were away from your work desk this morning. There were a total of twelve patches, six of which were listed as "critical."

"While it is not unprecedented for the vendor to issue a dozen patches, this is on the high side. But at least the vendor can console itself that it did not have to issue any patches for its flagship OS Vista, which only hit consumers at the end of last month. Still, it’s only early days."
