5. Give Yourself High Marks
The first time many of us opened up the Windows Experience Index (WEI) and saw the pitiful score, we were ticked off-at least I was. A brand new laptop should have a higher score than a 2.9.
As you learn more about how the rating works, however, the score probably won't sting as much. To calculate the WEI, Vista takes the lowest of five scores that relate to your processor, RAM and so on. Maybe that's the goal of the WEI -- to embarrass or anger us into spending more money on better hardware.
Figure 5. How is this for a WEI Score?
There are a couple of ways to increase your rating (besides shelling out thousands of dollars for upgrades). First off, run the test again. Sometimes just running it again will boost you over the three mark. I ran mine again and got a 3.1. Another tip is to turn off your Aero glass interface, which will boost performance. Or, you could go right into the .XML file that stores the results and give yourself a higher score.
The Windows System Assessment Tool (WinSAT), which is the tool that calculates the WEI, stores its output in the %systemroot%\Performance\WinSAT\DataStore. Each time you run WinSAT, it creates a new XML file and stores it in this folder with the assessment date at the beginning of the file name.
For example, a file might look like this: 2007-01-01 12.00.00.000 Assessment (Formal).WinSAT.xml. When you first open the folder, you might be shocked to see there are more than five results. In fact, WinSAT runs a variety of tests and assigns scores, but it will typically only show us the top five.
My research assistant Alan Wright took some time and tweaked the file to see if he could change it. "The first thing I would recommend is turning off the UAC for this procedure," he says. "Then open the file using WordPad (I used several editors but WordPad was the easiest to work with and didn't try to change the file format). You only have to change the top five scores to whatever number you like and close the file. When you go to look at your WEI settings again, it should show you the new number.
"If you stay below 5.9, your number will still have a blue background, but if you go too high it does change the background to grey, which isn't a big deal either way but does indicate a difference," he says. "To 'fix' this and make it go back to normal, I just deleted the file and rebooted my machine and then re-ran the test. It worked fine. I was back to my 3.1 rating. Knowing that I could tweak it, I went back in and gave myself a 4.0. That's how I feel today. Maybe tomorrow I'll be a 6.0."
Now why would you even want to do this in the first place? Well, for one thing, you learn a lot about WinSAT by playing with this. You also see that the testing process is a lot more detailed than you might have thought.
Really though, this is just one of those things that makes you smile, especially after seeing that 2.9 rating. To see some other scores that people are getting there's a site called

you and I know how to win that game.
