NoneAll versions of the Windows operating system that run on 64-bit architecture
This tag covers all general programming issues for software running on Windows 64-bit operating systems (XP, 2003, Vista, etc.).
For programming questions about 64-bit architecture that are platform and operating system independent (in other words, for Linux, Mac, Windows, etc.), simply use the x64 tag.
Check serverfault.com or superuser.com for general questions on the 64-bit architecture and its hardware.
See Microsoft's Programming Guide for 64-bit Windows for more information on programming for Windows 64-bit architecture.
