Windows 7 Support for the Department of Defense will be extended, just like XP support was no doubt! That's the words out of my customers mouths. If you listen to their requests, I've reinstalled Windows 7 as the SIPR and NIPR primary system for over 1k computers this quarter alone! Windows 7 is the replacement for XP. There was Millennium, Windows 2000 and Vista between these 2 OS and the DOD will get their way!! Windows 9 will replace Windows 7, only if it looks and feels the same way. The DOD doesnt use 3rd party programs like Pokki to try and get the feel of Windows 7 back, they reimage computers to Windows 7 and drop Windows 8 completely. There is a marked shift from Dell to HP computers since HP offers to drop back to Windows 7 with all their DOD purchases!!!
