Despite having updated regularly and checked that my drivers are up to date, I am not being offered Vista SP1 or SP2. I have gone through http://support.microsoft.com/kb/948343 but can find no reason why I should not have been offered SP1. I have also uninstalled Windows messenger live, as the article suggests that it could prevent installation of SP2.
Any ideas how I can update Vista to a supported version. I could try downloading the standalone package and installing it but microsoft suggests not doing that for a single computer.
Any help would be appreciated.
