Vista - Vista Business Service Pack 3???

Hello,

I wonder why my Windows Vista Business is showing Servive Pack 3 as I only installed SP1 last year?

Can anybody help to solve this?

i would not worry to much about it mate as long your pc works fine and well

I have similar problem with Vista Home Premium. I don't mind having the fake "Service Pack 3" but I now I can't installed the real Service Pack 2.

I get this error at the very beginning of SP2 installation: "A more recent version of Windows Vista Service Pack 2 is already installed".

Microsoft believes it's due to previous SP2 beta installation and suggests I remove the beta but I never installed any SP2 beta on my system.

Hope someone else could help.

Yupe I have exact the same problem, except I never installed any SP2 beta.

Pls refer to this.

I have contacted Microsoft and they better have a solution on this.

If you get other advice from Microsoft please post it here.

Thanks in advance.

After googling for a while, I manage to figure out the solution to the issue.

The hex values of the "CSDVersion" subkeys to the following registry keys need to be changed from "300" to "100":

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Windows
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\Windows

Hex value of "100" indicates "Service Pack 1", "200" is "Service Pack 2", "300" is "Service Pack 3", so on and so forth. After the system "reverting" to Service Pack 1, Service Pack 2 will install without a glitch.

Hope this work for you too.

Yes, this works for me, I manage to install SP2 already.

Thank you so much!!!
