Microsoft issues a record 64 vulnerabilities in Windows, Office, Internet Explorer, and other software. The 17 updates tied a record set late last year, but easily beat the October 2010 mark for the total number of flaws they fixed. The company also delivered a long-discussed “backport” to Office 2003 and Office 2007 that brings one of the newer security features in Office 2010 to the older editions. Microsoft and virtually every security expert pegged several updates that users should download and install immediately. Microsoft also issued patches for Excel, PowerPoint and multiple bits of Windows.”]
