“We wanted to let you know that an update was released earlier today that will improve Internet Explorer’s reliability for users running the Windows 7 Beta. The update is now available via Windows Update, and can also be downloaded via Microsoft Update.
In this post we’ll discuss how we used the information that we’re receiving from Windows 7 Beta customers to determine the reliability fixes to include in this update.
We use the term “reliability” to broadly encompass all types of stability problems including crashes, hangs, memory leaks, etc. When we measure reliability we rely primarily on instrumentation built into Internet Explorer 8 and Windows 7. For example, the Customer Experience Improvement Program enables us to better understand how customers use our products, and Windows Error Reporting provides detailed information about the problems customers encounter. Shortly after the Windows 7 Beta became publically available these systems began to send information back to Microsoft.”
