Viewing Other Information
If you're like me, you sometimes ignore the many messages that Windows is known to display. If you want (or need) to go back and reread some of these dismissed messages, click the View Archived Messages link in the Action Center's task list. This displays all the Windows messages for problems that have been reported to Microsoft.
In addition, Action Center can display information about your system's performance—in particular, the Windows Performance Index (WPI). This is a rating of how suitable your specific system is for running Windows 7, on a scale of 0 to 5. The higher the score, the better, of course.
To display your system's Windows Performance Index, shown in Figure 5, click the View Performance Information link in the Action Center's task list.

Figure 5 Viewing the Windows Performance Index
The WPI is based on five individual scores for specific areas of performance:
- Processor, in terms of calculations per second
- Memory (RAM), in terms of memory operations per second
- Graphics, in terms of desktop performance for Windows Aero graphics
- Gaming graphics, in terms of 3D business and gaming graphics performance
- Primary hard disk, in terms of disk data transfer rate
Know, however, that your base score is determined by the lowest subscore. So even if your system has a fast processor and lots of RAM, if you have a sluggish graphics card, that factor alone will determine your overall score.
