Windows – Backup before installing Windows Vista SP2


Is it necessary to back up data before installing Windows Vista Service Pack 2 (SP2) from online updates?

Best Answer

No, it is not necessary, but it is recommended.

Service Packs are many updates all packaged together, and it only installs the updates in the SP that are not already installed or up-to-date. However, there is always the chance that an update can mess up your computer, etc, and with a SP, you should backup, just in case.
