Those of you following things closely may already know but build 18000 has officially be outed as the full RTM version of service pack 1 (see If you’ve got Refresh 2, You’ve got RTM at Geek’s Anatomy)
You can get this straight from microsoft themselves through windows update using the following steps. Be aware that there are reported driver conflicts with some systems so do this at your own risk and please backup your system. That said, this is the official super ultra final build that will appear for everybody else next month.
1. Create a new text file and call it "vista.bat"
2. Edit the file and pop the following into it (and run it afterwards obviously):
@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 dcf99ef8-d784-414e-b411-81a910d2761d /f
IF NOT %errorlevel% == 0 ( goto ERROR)
:SUCCESS
%SystemRoot%\system32\wuapp.exe
goto END
:ERROR
@echo.
echo ===========================================================
echo error
echo ===========================================================
@echo.
pause
goto END
:END
3. now go to windows update and manually check for updates
4. you should now see the first of two pre-sp1 updates - install and reboot as required for each.
5. finally you should see "Windows Vista Service Pack 1 Release Candidate 1 - Build 6001.18000". That's the big one kids. For my x64 english ultimate system it's 126.1MB
