A machine running Windows XP Professional x64 Edition cannot be directly upgraded to Windows Vista because the 64-bit Vista DVD mistakenly recognizes XP x64 as a 32-bit system. Windows XP x64 does qualify the customer to use an upgrade copy of Windows Vista or Windows 7, however it must be installed as a clean install.
In Windows XP and earlier, the Windows installation source ships four kernel image files to support uniprocessor systems, symmetric multiprocessor (SMP) systems, CPUs with PAE, and CPUs without PAE. Windows setup decides whether the system is uniprocessor or multiprocessor, then, installs both the PAE and non-PAE variants of the kernel image ...
The first, Windows XP 64-Bit Edition, was intended for IA-64 systems; as IA-64 usage declined on workstations in favor of AMD's x86-64 architecture, the Itanium edition was discontinued in January 2005. [57] A new 64-bit edition supporting the x86-64 architecture, called Windows XP Professional x64 Edition, was released in April 2005. [58]

The kernel connects the application software to the hardware of a computer. Kernel Patch Protection (KPP), informally known as PatchGuard, is a feature of 64-bit editions of Microsoft Windows that prevents patching the kernel. It was first introduced in 2005 with the x64 editions of Windows Vista and Windows Server 2003 Service Pack 1. [1]
The default behavior is to boot a 64-bit kernel, allowing both 64-bit and existing or new 32-bit executables to be run. A 32-bit kernel can also be manually selected, in which case only 32-bit executables will run. The isainfo command can be used to determine if a system is running a 64-bit kernel. For Solaris 11, only the 64-bit kernel is ...
While it is not a major problem for the x86 architecture because of the popularity of Windows XP x86-32, many vendors choose to make 64-bit driver versions only for Windows Vista – which means that Linux systems using the x86-64 architecture are unable to use such networking devices (they can neither use XP x86-32 NDIS5 because they are 64 ...
The Windows installation procedure determines which ones are appropriate for the current platform and copies it to the hard drive, renaming it to hal.dll if necessary. Among the criteria for this selection are: the presence of an ACPI -compatible BIOS, the presence of an APIC , and whether or not multiple processors are present and enabled.
