Windows Vista SP1 is set to be released any moment. If you want to get a jump on the download and install that takes multiple restarts and a full 2 hours. At least for me. However once it is installed Service Pack 1 really feels smooth.
Here is the script to change your registry to allow for the windows update download:
@echo off
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp1 /f > NUL 2>&1
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSP1 /f > NUL 2>&1
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp1 /v Beta1 /t REG_SZ /d dcf99ef8-d784-414e-b411-81a910d2761d /f
IF NOT %errorlevel% == 0 ( goto ERROR)
:SUCCESS
@echo.
echo ===========================================================
echo Windows Vista SP1 registry key has been set successfully.
echo Please check for updates in Windows Update.
echo ===========================================================
@echo.
goto END
:ERROR
@echo.
