IE7 update available for Vista while Windows XP users wait

Steve Reynolds, Microsoft Internet Explorer Program Manager, announced on the Microsoft Internet Explorer Blog that an update for Internet Explorer 7 is available. The IE7 update "addresses an issue experienced by some users where CPU usage is high when they are navigating a page that contains multiple frames or when multiple frames are navigated simultaneously". If you have experienced any such performance issue, Microsoft is encouraging you to download and install the update.

While a software update is not unusual, I couldn't help but notice the following words from his post (with my own emphasis is in bold).

This update is now available on Windows Update for Windows Vista users and will be made available in February for Windows XP and Windows Server 2003 users. All users can download it now here along with related KB article 928089.

You can't help but wonder how much Microsoft marketing is or isn't involved in this decision. What better reason for a user to update from Windows XP to Windows Vista than the fact that security and performance updates for Windows XP will be arriving behind Microsoft's new favorite son. Sigh...
