I decided to reinstall my D820 with 64 bit version of Windows Vista as involvement act with Gadi. 13 minutes of installation. All hardware was found and all drivers were installed (this why I love Dell). The same score as was with 32 bit version - 3.2. Fist run of Windows Update = 38 fixes (about 130MB, only required updates, downloaded and installed within 55 minutes including first restart). Another turn of Windows Update brings me additional 2 fixes (63.9MB of driver's updates and 10 minutes ). It downgrade my computer to 3.0. Now I have to add my computer to domain. It was done via VPN over WiFi and took about 10 minutes including security check, policy update and IPSec. After Vista was activated, come Office's and Live Suite turn to be installed.
Office installation took about 2(!) hours. Well, I do not know why it happens, however, let's go on and install VSTS 2008. The first step of VSTS installation required me to restart my computer twice. It looks like there are issues with "Microsoft .NET Framework v3.5 (x64)". However, after I "run as Administrator" the Visual Studio installer, the problem disappears. It looks like there are some files become locked, when running the installer without elevated permissions (THIS IS BUG). After the first step passed, I wait for another 35 minutes for VSTS to be completely installed. To be honest, in x64 HxMerge works a bit faster, then on x32 platform. Additional 15 minutes of MSDN library.
Well, overall experience of installations was rather bad, but much worse is how x64 works. More then half of system processes (see the example of such service - Console IME at screenshot) are working in simulation mode, so performance of the system is sucks.
What will be my next step? Probably, uninstall of x64 bit version of Windows Vista and installation of x32 bit system. I can not see real advantages of using x64 due to fact, that this software is not ready for public use and waste your system resources.
What do you think about this point?
