如何在线更新Windows Vista SP1最新版

　　在线升级Vista SP1最新版的原理和以前的在线升级 Vista SP1 RC的原理一样，需要用管理员权限执行一个cmd或者bat文件。

　　该cmd 的文件内容如下：

=========以下为cmd文件内容=====

@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 c1ff1d2f-c61e-4f27-b68c-722061c201a5 /f
IF NOT %errorlevel% == 0 ( goto ERROR)

:SUCCESS
@echo.
echo ===========================================================
