Download and Install Windows Vista SP1 RC1 via Windows Update

Windows Vista Service Pack 1 Release Candidate 1 (Vista SP1 RC1) can now be downloaded and installed via Windows Update (see announcement). The previous two hacks to install SP1 beta and SP1 RC Preview no longer works, and must be removed to the official Vista SP1 RC to be shown up and available to install in Windows Update. It’s also recommended (MSDN WU upgrade instruction required to uninstall KB936330 (SP1), but user experiences confirmed that it’s possible to upgrade install) to uninstall “Service Pack for Windows (KB936330)” in “View installed updates.”

To trick to download and install Windows Vista SP1 RC1 (v.668) via Windows Update is to download the following batch command script, which taken care of everything - remove old registry keys and add in new registry key to Windows Update to target your machine as a valid Vista SP1 RC testing computer.

Download SP1RC_WUHack.cmd

Update available: Windows Vista SP1 RC Refresh (v.774)

Update: Microsoft has made available Windows Vista Service Pack 1 RC Public Availability Program which also applied the registry hack to get Vista SP1 RC installed.

Right click on the SP1RC_WUHack.cmd and then select “Run as Administrator” and confirm User Account Control prompt to merge the registry values and keys to the system registry. Then go to Windows Update and check for updates. The hack to download Vista SP1 RC from WU works on English version of Vista, and it comes with all Vista languague MUIs. Thus users should be able to install Vista SP1 RC1 on any editions of Vista regardless of language locale. Else wait till official release of SP1 RC next week for standalone installer package, or follow the trick to force service pack for non-English Vista to show up in Windows Update.

All users, especially those never install Vista SP1 Beta or RC1 Preview via Windows Update, will likley have to install 3 important prerequisites updates/hotfixes before Windows Vista Service Pack 1 is offered, as they’ve been updated. The 3 updates is Update for Windows Vista (KB935509) - v1.008, Update for Windows Vista (KB938371) - v1.028, and Update for Windows vista (KB937287) - Build 6001.17052 (x86 or x64).

Windows Vista SP1 RC1 Important Update

Windows Vista Service Pack 1 RC is near stable and near perfect release of SP1 test code before final release of SP1 in the first quarter of 2008. However, although it’s more stable than most previous version of betas, care should be taken before installing it, especially on production system as it may still causes system errors. This release also expire on June 30th 2008, but by that time everybody should be upgraded to final release of SP1 for Vista.

    It shouldn’t, officially, but there are reports on random cases that activation done with OEM BIOS emulation toolkit was been deactivated. Vista loader will probably still work. If you try to upgrade do let us know the result.

    1)You have to go to windows update and “Check for updates” again, the third download will eventually show up; 2) Once installed don’t forget to restart the computer, immediately after logging off you could probably see this message “Configuring updates 1 of 3 00%”; 3)After the computer restarts repeat step 1.

    Note: SP1 RC1 would disable OEM BIOS emulation

    Note: If windows deactivated after installing Vista SP1 RC1, you may still use vistaloader to reactivate it. So no problem.
