only English version of sp1 are release..
juz wait for other language version release 

3.5gb is the real 1.... 4gb is just to clear confusion of users....... if u install 4gb on ur 32bit windows OS... the actual utilize is not 4gb... instead only about 3gb+ is used.... 4gb minus out ur hardware memory such as 3dcard and souncard and etc.... for example let say ur 3dcard is 512mb... so it only use 3.5gb for ur system....

vista sp1 stated 4gb is to clear the user confusion and stop alot of user from asking "eh i instlal 4gb and i get only 3gb+ ram, WHY????"

memory remapping = using 4gb memory on 32bit OS method, is unable to use in windows if im not wrong.... therefore want to use 4gb or more memory? go 64bit OS

erh, if i'm using 2gb of rams now, with vista sp1, then upgrade to 4gb, will i need to reactivate my vista?
asked in the help desk, but some fag replied with unrelated stuffs

my boot time is faster around 1min+ compare to last and i did a clean install 1st. also changed a new hdd la. so far sp1 giving me no prob. and it faster alot when copying large files

Ok back to the question whether my vista is sp1 equipped or not. Please find the attachment. They said we can view it in the system properties. But I can't see it even though there is nothing more to update.
