Unless you need more than about 3.5GB of RAM. 32 bits can only address 4GB (and part of that 4GB address space is used by your graphics card). Even if you put 16GB of chips into the computer, a 32 bit operating system will see only 4GB.
windows 7 ultimate is the best OS in win 7 its give many advanced feature like bitlocker,usb as a ram, volume, PRD, etc....
Nope, USB as Ready Boost, which puts the page file on the USB to speed access up a bit. If you have 4GB of RAM and add a 4GB USB stick, you still have 4GB of RAM. Bitlocker is a program, it's not part of Windows. (So are all the other "additions" with Ultimate. Windows is still Windows.)
I HAVE BEEN USING WINDOWS 7 ULTIMATE 32-bit edition for 2 YEARS AND HAVE'T FACE ANY PROBLEM DURING THIS PERIOD. IT IS BEST FOR ME THAN OTHER TWO.
i am using W7 Ultimate and thats the best OS i have ever used ... xp was not bad but Win7 is MUCH better ... works really great for me i dont know about Win8 but not ready to upgrade "if it is working, don't break it" is my rule
windows xp is much more stable now with more arising new softwares on the internet today, they are always compatible to install and it's more faster and user friendly to new users of a computer
