修改注冊表提前更新到VistaSP2

　　不僅僅是測試者其實您也可以提前更新到SP的PreBeta版本方法和之前SP的提前更新一模一樣:修改注冊表
只要把以下代碼寫成任意名字的bat批處理文件就可以在自動更新裡面就可以看到SP

　　@echo off

reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp /f > NUL >&
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\WowNode\Microsoft\ Windows\CurrentVersion\WindowsUpdate\VistaSP /f > NUL >&

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp /v Beta /t REG_SZ /d CACCCFABDBEDF /f
IF NOT %errorlevel% == ( goto ERROR)

:SUCCESS
@echo
echo ================================================== =========
echo Windows Vista SP registry key has been set successfully
echo Please check for updates in Windows Update
echo ================================================== =========
@echo
goto END

:ERROR
