Can't uninstall previous SP1 Beta

I purchased a computer in November with Vista Home Premium. When Microsoft opened the public beta, I installed it. I later upgraded to Vista Ultimate. Now the new release candidate is available, I cannot find the SP1 in Programs and Features to be able to uninstall it so that I can install the refresh. System and Maintenance says I am running Windows Vista Ultimate Service Pack 1, v.668, which I believe is the first public beta. Thank you in advance for any assistance.

When I search for KB936330, I get "No items match your search."
That KB does not show up in my list.

When I use the syntax in the posting:

start /w pkgmgr /up: VistaSP1-KB936330~31bf3856ad364e35~x86~~6.0.0.<build number>​

and the 17052 build number found in the registry, the space after /up: causes an error:

Operation failed with 0x80070057
The parameter is incorrect.​

and when I remove the space, no matter what build number I use, it immediately returns to the prompt - no error and no activity.

I believe this issues is because my restore point that was created when I installed Vista SP1 RC has been over written. Can someone please confirm that if your restore point is gone that you're screwed?

I logged an e-mail with HP, who I bought my PC from and they sent details and clearing traces from the resgistry. I have not tried it yet:

My computer is a 64-bit system (Intel Core 2 Quad Q6600) running the 32-bit version of Vista Ultimate.

I have no Vista SP1 in the install keys. I do have it in the Windows Update keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\VistaSp1

Contains the key:

Beta1 with REG_SZ value c1ff1d2f-c61e-4f27-b68c-722061c201a5

Windows Update only shows 13 items, none of which is the Vista SP1. I downloaded Windows6.0-KB936330-wave1-X86.exe and it says "Windows Vista Service Pack 1 is already installed." My System and Maintenance->System shows

"Windows Vista Ultimate
Copyright...
Service Pack 1, v.668

Help->About Windows shows:

Microsoft Windows
Version 6.0 (Build 6001: Service Pack 1, v.668)
...

But the package 936330 doesn't show up for me to remove. Is there a Windows Update or regsitry hack to clean up this mess?

Windows Update -> View Update history does show:

Update for Windows Vista (KB937287) - Build 6001.17128 (x86)

Is that significant?
