The update that tackles one or more flaws in InfoPath will also patch SQL Server and Visual Studio development toolset, Microsoft said in the notes it published today announcing next Tuesday's slate.

Several of the updates will patch Windows 7, Microsoft's newest operating system that continues to gain users. According to Web metrics company Net Applications, Windows 7 now accounts for 26% of all operating systems currently in use.

Eight of the 10 Windows updates affect Windows 7, with five of those marked critical. The other three were tagged important by Microsoft.

"The number of Windows 7 updates isn't surprising, but par for the course," said Storms. "A lot more people are moving to Windows 7, and the bugs are going to follow the user base."

Storms suspected that the updates for Silverlight, .Net and Visual Studio may have something to do with GDI+ (graphics device interface), the core component that handles graphics rendering in Windows. "It may be something that Microsoft needs to fix so developers can redistribute updated software," Storms speculated. "If so, it wouldn't be surprising, but it would also be disappointing. Microsoft's had its fair share of GDI vulnerabilities."

Microsoft last patched GDI in April.

Also today, Adobe announced that it will ship updates for Reader and Acrobat on Tuesday. Although Adobe did not specify how many bugs will be patched in the update, several in Flash Player -- Adobe's popular browser plug-in -- that have been patched previously still must be addressed in Reader X, the newest edition that includes anti-exploit "sandbox" technology.how

The 16 updates from Microsoft will be released at approximately 1 p.m. ET on June 14.
