An update is available that will help improve the performance and reliability of Windows Vista SP1.

This update includes the following improvements on a Windows Vista SP1-based computer:

• The stability of Windows Vista SP1-based computers by addressing some crashes that may occur when you try to check e-mail by using a POP3 e-mail client such as Windows Mail or Mozilla Thunderbird.

• The reliability of the Windows Vista SP1 based-computers by addressing some problems that occur when you delete user accounts by using the User Accounts item in Control Panel. When this problem occurs, the system may stop responding (hang).
• The reliability of Windows Vista SP1-based computers that experience issues in which large applications cannot run after the computer is turned on for extended periods of time. For example, when you try to start Excel 2007 after the computer is turned on for extended periods of time, a user may receive an error message.
• The reliability of Windows Vista SP1-based computers by reducing the number of crashes that may be caused by the Apple QuickTime thumbnail preview in Windows Live Photo Gallery.
• The performance of Windows Vista SP1-based computers by reducing audio and video (AV) stuttering. Such AV stuttering may occur when the audio or video component is streaming high definition content from a Windows Vista SP1-based computer that has a NVIDIA network adapter nForce driver version 67.5.4.0 that is installed to a Windows Media Center Extender device.
