First of all, windows 7 is not any major upgrade from vista. its more a like a slightly tweaked version of vista itself. second thing, about microsoft admitting vista to be a failure, most people dont see it microsoft has played the biggest gamble. .they admitted vista is failure, launch windows 7 with minor tweaks, supposedly giving users a whole new OS. windows 7 does not have any kind of better memory management or anything.. its just that in windows 7, lot of unneeded background services that used to run in vista, have been turned off by default. u can manually do this in vista too.. just open 'services.msc' from the run command. turn off a few glossy and memory eating windows visual settings like glass effect, fading effect etc.. make your windows look like windows 98, and see for yourself the difference in working speed..and your vista will be just fine..
On default vista settings, the idle processor usage stays above 6 %, averaging at around 10 to 12 %. whereas after the tweaks, my idle processor usage came down to less
than an average of 1 to 2 percent.
I had vista on my laptop, upgraded to windows 7 for just 2K (relative working in microsoft --- employee quota. . heheh.) and there wasnt really much difference.. .i noticed, that 7 was just vista, with lots of background things turned off .. which i had done in my vista too. so no visibile performance upgrade..
if u think ur vista's running slow, all u need to do is make a few tweaks.. can help u with that if you're interested..
my suggestion is to stick with vista, make the tweaks and not spend money unnecessarily on windows 7..
