HOW TO MAKE WINDOWS VISTA TO WORK FASTER IF YOU HAVE LOWEST CONFIGURATION PC

This trick i call "FOOLING VISTA". It works greatly and am not sure whether it has been discussed by any one or not. If you have windows vista and have low config pc and you want your pc to perform faster then this is perfect way. Now what you need to do
*you might have seen rating when you click properties on my computer. These ratings determine the perfomance of your system. If ratings aren't shown then there will be a link showing 'rate this computer' and after your computer has been rated close the window.
*click on my computer or simply go to search and type the word 'WINSAT' CLICK IT
NOW YOU WILL SEE A FILE NAMED DATASCORE WITH THE DATE YOU RATED YOUR SYSTEM.
*COPY THE XML FILE IN DATASCORE ON DESKTOP
*NOW EDIT THIS FILE WITH ANY ADVANCED HTML EDITOR LIKE WORD PAD ETC.
*YOU WILL SEE FIELDS LIKE THIS THERE "abc<3.6>xyz" Note abc and xyz is just illustration there could be ram or graphics or anything else. YOU JUST NEED TO CHANGE THAT SCORE TO 9.9 I,E 3.6 REPLACED BY 9.9
*you need to change this value everywhere you see those fields ie the value of your ram or graphics to 9.9

*NOW SAVE THIS FILE
*COPY THE SAVED FILE BACK TO DATASCORE AND REPLACE EXISTING FILE.
*RESTART YOUR SYSTEM
*SEE PROPERTIES BY RIGHT CLICKING ON YOUR COMPUTER.
*YOU WILL SEE THAT YOUR RATINGS ARE NOW 9.9 AND YOUR SYSTEM WILL PERFORM BETTER.
