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

@echo.
goto END


:ERROR
@echo.

echo ERROR setting the Windows Vista SP2 registry keys
echo Please run this script as Administrator (right-click, 'Run as Administrator').
echo ================================================== =========
@echo.
goto END


:END
pause
pause

2. Now, right click on it and select Run as Administrator.

3. Windows should start updating now.

4. If everything goes fine, enjoy with Vista SP2.

As SP2 is in pre-beta stage, it’s a good practice to create a restore point or backup to avoid future problems.

If Windows has not started updating automatically, follow this procedure to start the update:

* Type Windows Update in start menu search box and hit enter.
* In the left pane of Windows Update, click Change Settings.
* Select the option named “Install Updates Automatically” and click Apply to start the process.

WARNING: As with prior versions usual, is also here that inexperienced users away from this preliminary version should leave.Even those who deal with Microsoft beta's know, should be aware that it is a very early test edition of Vista SP2, whose massive installation problems may bring with it - loss of data can not be excluded.
