Will the new version of windows have 64-bit support built-in or is it going to be packaged as a seperate version. Will microsoft release one version of the new windows as 32-bit and one version as 64-bit?
You can only install one version at a time. I heard around the net from people, the 64bit will be geared towards businesses. You may find that most games and video cards do not support it or release drivers for it, especially if its geared ONLY for business use.
Microsoft is coming out with Vista that will fully support 64-bit. I agree there is no point to use 64-bit Windows XP, however 64-bit is far from being dead. Once Vista gets released that will breathe new life into it.
