Microsoft quietly patches Windows Vista

Software giant won't comment on rumored Windows Vista SP1.

Microsoft has quietly released two hot fixes on its Web site for Windows Vista. It has not, however, pushed these out to Windows Vista users via the Windows Update process. Nor would Microsoft comment on rumors the two are related to a yet-to-be-announced Windows Vista SP1 release.

One hot fix is considered a performance update. Designated KB938979 this update addresses a variety of media and photo-related issues, including the inability to edit photos in the raw file format from Canon EOS 1D and Canon EOS 1DS cameras.

The other hot fix is also media related, though KB938194 also addresses problems experienced by the print spooler and when the Windows Vista machine goes to sleep with an active Point-to-Point Protocol (PPP) connection.

In an e-mail to CNET, a Microsoft representative said "the two updates (KB938194 and KB938979) will be available on Microsoft's download center today and broadly available via Windows Update in the near future." Many have interpreted "the near future" to mean the next Patch Tuesday, which is scheduled for August 14.

As for Windows Vista SP1, Microsoft wouldn't comment directly except to say "since Windows Vista launched, we have continued working with partners to improve overall device coverage and application compatibility."
