On my big box, Core2duo, 8 GIG RAM, many other high-end features, I am running WinServer 2k8 R2, and use Win 7 from a VM, from the moment I click "power on" to C-A-D, its 29 seconds. Now I also am testing on older hardware, a Dell Optiplex GX240, P4 1.6, 384MB RAM, and a 5400 RPM HDD. This machine choked on XP, but ran it decently. Now, with Windows 7, it will go from "power on" to C-A-D in 54 seconds, thats amazing! Considering you had time to go get a cup of coffee and sit at the water cooler for a moment on your way back, when booting XP. Now on my laptop, which is Turion 64x2, 1024MB RAM, non-shared vid ram, 5400 RPM 100 GIG HDD, that was built for Windows Vista home premium, that took (from a fresh load of the OS) 75-110 seconds of total load to C-A-D screen. Im honestly in a state of Shock and Awe, as my Technet downloads are almost 50% the size of VISTA, 2.3 GIGS?? and VISTA ULT was pushing the max mark! It feels like a completely revamped reworked, cleaned up version of what Vista could have been, had it stayed in dev for 3 more years. Great job M$, Im glad you are actually listening to your users!
