On my PC
Phenom II x4 965 overclocked to 3.8GHz
4GB ddr3 1600 memory
1TB 7200RPM hard drive
GTS 250
windows xp boots in about 13 seconds (thats to be at a point when no additional loading happens)
just about every option in the OS opens instantly (the same is not the case for windows 7)
(My 3dmark 06 score in higher) (cant run a higher end 3dmark since they dropped windows xp pretty quickly
I use windows xp for most of what I do and windows 7 is just for certain games like just cause 2 which will not run on windows xp
If you are a user who mostly uses their computer for basic things which do not really need the windows 7 specific features like dx 10 and 11
what do you gain by using a OS that uses more resources on it's self, thus taking resources away from the programs you want to run?
for windows xp, it is extremely light and does what a OS is suppose to do, which is get out of the way so you can you run your programs.
if you have been running windows 7 for a while, try installing windows xp as a dual boot.
you will feel that windows xp is much more snappy because to use any of it's build in functions, less hard drive IO's are needed. When loading from a hard drive, it will always be faster to load less than it is to load more.
Microsoft needs to learn a lesson from professional application companies.
Look at programs like maya, adobe aftereffects,adobe premier pro and many others, you will see that new versions are faster than the old versions, even when requirements go up, generally you will notice that the there is a shift in resources, the main app uses less resources so that the more time critical components will have more resources, thus increasing speed.
For a professional program, time is money and people wont buy a program that will cause time to be wasted by taking longer to get the same job done.
