微软提供在线更新升级到Windows Vista SP1

随本Vista SP1发布的还有一个CMD文件，通过它可以实现经由Windows更新完成SP1 RC安装。这个文件可是微软提供的，与之前泄露的CMD文件一致（不是"一样"）的，估计之前泄露的文件也是来自微软的。
只要运行一次该CMD文件，然后一直检查更新，直到发现sp1为止。但是，很重要，该方法似乎只针对英文系统有效。如果你不想费时更改系统设置的话，就只有等待公开版发布了。
CMD文件：

 @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 da2ba4db-dedb-437e-8e7e-104643454bb6 /f
