There are several ways that you can upgrade your computer to Vista SP2, but the way I recommend is to download the complete upgrade file and run that on your computer (rather than using Automatic or Manual Updates). Why? Because if there are any network problems, your installation will not be effected. Also, once you have it on your computer, you can put it on a CD for safe keeping.
To download Vista SP2, choose the link for your system:
- The download site for 32-bit versions
- The download site for 64-bit versions
