The display driver model from Windows 8.1 and Windows Phone have converged into a unified model for Windows 10. [43] A new memory model is implemented that gives each GPU a per-process virtual address space. Direct addressing of video memory is still supported by WDDMv2 for graphics hardware that requires it, but that is considered a legacy case.
The 25 characters of the Product Key form a base-24 encoding of the binary representation of the Product Key. The Product Key is a multi-precision integer of roughly 115 bits, which is stored in little endian byte order in an array of 15 bytes. Of these 15 bytes the least significant four bytes contain the Raw Product Key in little endian byte ...
Windows 8.1 is a release of the Windows NT operating system developed by Microsoft.It was released to manufacturing on August 27, 2013, and broadly released for retail sale on October 17, 2013, about a year after the retail release of its predecessor, and succeeded by Windows 10 on July 29, 2015.
x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [note 1] is a 64-bit extension of the x86 instruction set architecture first announced in 1999. It introduces two new operating modes: 64-bit mode and compatibility mode, along with a new four-level paging mechanism.

In-place upgrades are supported from most editions of Windows 7 with Service Pack 1 and Windows 8.1 with Update 1, while users with Windows 8 must first upgrade to Windows 8.1. Changing between architectures (e.g., upgrading from 32-bit edition to a 64-bit editions) via in-place upgrades is not supported; a clean installation is required.
The resulting implementation of the IA-64 64-bit architecture was the Itanium, finally introduced in June 2001. The Itanium's performance running legacy x86 code did not meet expectations, and it failed to compete effectively with x86-64, which was AMD's 64-bit extension of the 32-bit x86 architecture (Intel uses the name Intel 64, previously ...
