One small, but surprisingly useful invention that made its debut in Windows
Vista and is continuing to make its mark on Windows 7 is the Windows
Experience Index (WEI). This index was a quick way at seeing where the
different components in your computer stood against the best possible
Most advanced users already know exactly where their computer sits among
the wide range of “killer machines” out there, but the novice users may want
to know what kind of computer they have and what areas need improvement.
WEI was Microsoft’s way of solving this problem and also establishing a
system for measuring a computers requirements for software and games.
The index essentially uses five categories and gives each category a score
from 1.0 to 7.9. The categories include: Processor, Memory, Graphics,
Gaming Graphics and Primary Hard Disk. Although each category is given a
separate score, your base score or WEI score will be the lowest of the five
Start -> Control Panel -> Performance Information and Tools
right-clicking on the Computer link in the start menu -> selecting Properties
Then click on Windows Experience Index.
Performance Information and Tools
Your computer will be given a score based on the performance test that is
run during setup, but a new test can be run at any time and after any new
hardware installation by clicking on Re-run the Assessment on the bottom
right-hand corner of the Performance window
Windows Experience Index
This is my Windows Experience Index score.
The assessment time will vary depending on the system, but you will not
want to have any applications open or be running anything that would
lower your score.
While the WEI may be nothing more than a “mine is bigger than yours”
measuring tool, some users may find this Vista carry-over an interesting way
to troubleshoot performance hiccups and also as a way to buy software that
they know will run successfully.
