Before updating to Windows Vista SP2
Before updating to Windows Vista SP2, the following steps are recommended:
- Backup your files as described in Backing up Your Files in Windows Vista (in English).
- Create a restore point as described in Using Microsoft System Restore in Windows Vista (in English).
- If you have previously downloaded and installed a prerelease version of Windows Vista SP2, uninstall it using the steps described in Uninstalling Software in Windows Vista (in English).
Requirements for Windows Vista SP2
Your computer must have Windows Vista with Service Pack 1 installed and enough free disk space to install the update. The amount of free disk space needed varies by system. 5 GBs of free disk space should be sufficient for any computer. 5 GB is in addition to leaving 5% of the total disk size for use by Windows. In addition, you might be required to install a Servicing Stack Update before Vista Service Pack 2 installs.
Installing Windows Vista SP2
For people who use their computers in a home or small office environment, the best way to download and install Windows Vista SP2 is through Windows Update (in English). Downloading through Windows Update saves time and disk space by downloading only the files your computer needs - about 40% less than the full download.
In a larger business environment with multiple computers, download and save the full installation of Service Pack 2 to a CD or DVD. A full install of Windows Vista SP2 includes all files needed for compatible computers. Before downloading, you need to know which version of Windows Vista is currently installed on the computers that will receive the update - 32-bit, 64-bit, or both. Download the updates you need from the Microsoft Download Center for Windows Vista 64-bit (in English) or Windows Vista 32-bit (in English).
