Microsoft made quite a big deal about issuing 11 security updates this month to correct problems with Windows. Too bad it couldn't even get the updates right. The company now has revised one of those Aug. 11 updates, explaining that it had posted an incomplete version to its own download center.

Computerworld.com reported that this was the third time in the past two months that Microsoft has had to reissue a security-related update. Anyone who manually downloaded MS08-051 to patch Office 2003 should obtain the second version as soon as possible, Microsoft said.

Those who obtained the update via Windows Update or through their company's Windows Server Update Services (WSUS) server, or who updated other versions of Office, do not need to reinstall MS08-051. The update patched three vulnerabilities in PowerPoint, including one that Microsoft labeled "critical," its highest ranking.
