The base score is a positive integer that starts at 1 and can continue to grow as new technology comes out . For example, in Windows Vista, the maximum score was 5 .9, while in Windows 7, the maximum score is 7 .9 . Each of the subscores also has a rating . The System Capabilities section can be in one of three different states:

Understanding the System Performance Rating
Microsoft Global Technical Readiness platforms Team
t is important to note that the System performance Rating number indicates the general speed and power of a computer running Windows Vista. The rating per-
tains only to the performance aspects that affect how well features in Windows and other programs will run on this computer and does not reflect the overall quality of the computer. a higher performance rating means the computer will generally perform better and faster especially when performing more advanced and resource-intensive tasks than a computer with a lower performance rating. The rating system is designed to accommodate future advances in computer technology. In general, the standards for each level of the rating system stay the same (within tenths). For example, a computer that is rated as a 4 should remain a 4 unless the computer s hardware changed. as technology continues to improve, additional higher-level Windows Experience scores will be introduced, and new tests added.

Understanding Windows Error Reporting
Windows Error Reporting (WER) is the client component for the overall Watson Feedback Platform (WFP), which allows Microsoft to collect reports about failure events that occur on a user s system, analyze the data contained in those reports, and respond to the user in a meaningful and actionable manner . WER is the technology that reports user-mode freezes, user-mode faults, and kernel-mode faults to the back-end servers at Microsoft and replaces Dr . Watson as the default application exception handler .
note
WER in Windows Vista and later has support for any kind of problem event as
defined by the developer, not just critical failures as in Windows Xp.
Overview of Windows Error Reporting
The WFP is illustrated in the high-level flow diagram in Figure 21-20, with WER labeled as the Watson Client .
Step 1: Problem event occurs Step 2: WER plug-in code calls WER APIs Step 3: WER collects the bucketing parameters and prompts the user for consent (if needed) Step 4: WER sends bucketing parameters to the Watson back-end Step 5: If Watson requests additional data, WER collects the data and prompts the user for consent (if needed) Step 6: WER executes pre-registered recovery and restart functions if applicable, and the data is compressed and uploaded behind-the-scenes Step 7: If a response is available from Microsoft, a notification is shown to the user
FIgURE 21-20 Watson Feedback Platform flow diagram
A significant improvement of WER in Windows Vista and later versions is the concept of queuing . In Windows XP, WER reports could be sent only at the time the event occurred, with few exceptions . Beginning with Windows Vista, WER provides a flexible queuing architecture where users, administrators, and WER integrators can determine the queuing behavior of their WER events .
