Windows XP Pro 32-bit upgrade to 64-bit?
I installed Windows XP pro 32-bit(i think) onto my new pc. My new pc has 4gb of ram and i heard for it to recognize all 4gb you need 64bit. How do i check if my windows is 64 or 32 bit? If it is 32 bit is there any way to upgrade to 64 bit without losing the files?
