Windows Vista Service Pack 2 (SP2) provides support for more types of hardware and includes all of the updates that have been released since SP1. Note: SP1 must be installed before you can install SP2.
To upgrade to Service Pack 2, perform the following steps:
Before you update to SP2, make sure you have backed up all your work. In fact, having a complete backup of your computer is always a good thing and can save you hours of frustration and problems if something goes wrong. It you can't take the time to backup your computer, you probably shouldn't upgrade to Vista SP2.
Windows Vista SP2 is available for download and installation for both 32-bit and 64-bit versions. Here's what you need to know.
Before you can upgrade Windows Vista, you must know what version of Vista and Service Packs you have.
Download the correct version of Vista SP2 directly to your computer before you install it. Although you can use Automatic or Manual Updates to do this, the best way in my opinion is to have the complete upgrade file on your computer before you install it.
The actual process of installing the Vista SP2 Upgrade is easy. First, perform all the pre-installation checks - this assures you will have a great install. Next, perform the installation, by following the directions and prompts.
If you have problems you can either contact Microsoft for free support, or uninstall the SP2 upgrade. It's that easy.
If you decide that you want to uninstall Vista SP2 from your computer to restore your computer to its previous state, perform the following procedure.
