I have just accessed the Microsoft update site to look for the patch to lock out the Blaster virus and it asks whether my Windows XP is the 32-bit edition or the 64-bit edition. Anyone know if Windows XP Home = 332-bit and presumably Windows XP Professional = 64-bit?
you have the 32bit edition. the 64bit edition is for the Itanium processcor . xp pro is also 32bit in most cases. the itanium is only really used for servers and not found in your average desktop. 64 bit processcors for the desktop are drawing ever closer (the MAC lads have beaten the PC to it)
