How would you grade Microsoft security initiative?

This CNN article says that Microsoft initiative to improve security did not really helped much. Do you agree? Have a read on the full article to see why the author predicted a grade D minus, but gave an actual F at the end of the year...

The latest round of scary things happened last week, with the SQL worm doing the rounds on the internet. It hit a year after Microsoft Chairman Bill Gates sent a company-wide e-mail saying Microsoft would make boosting security of its software a top priority.

The article says Microsoft placed responsibility on computer users who failed to install a patch that had been available since at least last June.

In theory, it's true... And the whole nature of software development implies faults will be present. Blame it on Microsoft alone does no good for the whole industry. Other companies have the same sort of problems. Just check security e-mail lists to see how many exploits are available and being used every day.

"The single largest message is: keep your system up to date with patches," Microsoft Chief Security Officer Scott Charney said.
