Hello, I would like to update my Vista DVD but as I often reinstall on various friends and families computers, I would like to keep the option to install all the versions (Ultimate, Home Premium, Home Basic, Business etc etc). So having read these forums, I get the idea that when applying all the updates I can: 1. Choose any of the versions e.g. Ultimate to update with all the latest .msu files 2. Choose to "rebuild all" instead of just the version I chose a few steps earlier (e.g. Ultimate) Is that correct that I will now have each of the versions fully updated and available to install depending on the product key on the computer I want to install it on? If not, then is there an easy way to make it so? Cheers
