I am now running windows vista 64. Which has been surprisingly simple how ever I have run into a few issues. Windows Explorer went insane and ignored the open in same window setting (note open in new process option was set to false.) resulting in a new window pre directory. I find life impossible in that situation. After numerous attempts to correct this via registry edits, I failed. Having given up I installed xpore2 as a replacement. ( great program I always wanted to filter my directory to only one file type) I now find after a reboot Windows Explorer works correctly and recycles the the window when displaying a new directory.
I have also found that you cannot just install sql management studio 64bit. you need to run(as admin) dvd drive:\Tools\Setup\SqlRun_Tools.msi otherwise you go through all the motions but nothing gets installed.
