Windows Vista Update & Service Pack Install Problems

OK. Loads of problems.
Machine is running Vista SP1. SP1 installed fine when it was released. These problems were identified trying to install SP2.

Windows Update isn't working - hover over the icon in the system tray and it says Windows Update Can't check for updates. Hasn't worked in months by the looks (Windows Defender updates still go)
Go into Windows Update, click check for updates and I get an error :
Code 80070490 Windows Update encountered an unknown error.
Try to install new windows update agent and get error :
Windows Update Agent Installer encountered unrecoverable error.
Service Pack 2 installation fails with :
Installation was not successful :
Element not found:
Error ERROR_NOT_FOUND (0x80070490)

Installed the system readiness tool that is recommended to fix SP1 issues, installed ok - no fix.

Anybody got any ideas?

Cheers.

According to Microsoft Knowledge Base (http://support.microsoft.com/kb/958044)

Cause: This issue may occur if there is corruption in the Component Based Servicing (CBS) manifest.
Painful Solution: To resolve this issue, you must perform a repair installation of Windows Vista or Windows Server 2008. Performing a repair installation will restore the current Windows installation to the version of the installation DVD. This also requires the installation of all updates that are not included on the installation DVD.

And there's a tool from Microsoft that claims to help solving windows update problems (http://support.microsoft.com/kb/947821) you might want to check it too..

However there's another solution that could be simpler and that might work:

Hope this helps :)
