  11. Now save the following as a file with .reg extension, then run it as the registry hack to download and install Windows Vista SP1 Beta:
    @echo off
    reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp1 /v Beta1 /t REG_SZ /d 37d55f36-65d6-4fe4-9dc7-892fcbe6222b /f
    reg add HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSP1 /v Beta1 /t REG_SZ /d 37d55f36-65d6-4fe4-9dc7-892fcbe6222b /f
    echo Vista SP1 registry key has been set. Please check for updates in Windows Update.
  12. After installing Windows Vista SP1, and if you want your system to revert back to its original display language setting, double click on the previously saved registry files from steps above to merge back the original values to the registry. Then go to Control Panel Regional and Language Options to set the display language back to your own language locale.

Note that after installing SP1 with procedure above and switch back to non-supported language locale, some system components that are using the language packs may fail or prompt out run-time error dialog box, such as when using Group Policy. However it shouldn’t affect general usage of Windows Vista.
