Few days ago I posted about early beta build of Windows Vista SP2 being released to private beta testers, and as usual
we now have a simple hack which allows users to get their hands on this
pre-build of Windows Vista Service Pack 2 before everybody else
directly from Windows Update servers.

To enable the early download access hack simply follow the procedure as described:

1. Copy the following batch file code to a text file and save as "Download-Vista-SP2.bat", alternatively you can download this batch file here.


@echo off




reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp2 /f > NUL 2>&1

reg delete
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSP2
/f > NUL 2>&1




reg add
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp2
/v Beta1 /t REG_SZ /d C21A5C64-2530-CC19-042F-9ABDB4ED27F9 /f

IF NOT %errorlevel% == 0 ( goto ERROR)




UCCESS

@echo.

echo ================================================== =========

echo Windows Vista SP2 registry key has been set successfully.

echo Please check for updates in Windows Update.

echo ================================================== =========

@echo.

goto END




:ERROR

@echo.

echo ================================================== =========

echo FAILED to set Windows Vista SP2 registry keys.

echo Please run this script by right clicking and selecting

echo "Run as Administrator".

echo ================================================== =========

@echo.

goto END




:END

pause


2. Double-click and launch the batch file to apply the hack.
3. Now, start Windows Update and you should see the Vista Service Pack 2 there.
