Steam.exe (main exception): ERROR: copying SteamNew.exe to Steam.exe failed, Win32 Error 32 "The process cannot access the file because it is being used by another process."
Again, brand new Windows 7 setup and after grabbing the installer from Steam's website, I get this crap.
Problem was easily solved though. Rather than trying to run Steam from the shortcut again, go to your Steam folder and run "SteamNew.exe".
It'll run the new updater and let it finish. Once it's done, you can resume using the usual Steam shortcuts.
