If my computer is already running Windows XP Professional, do I need to install the WinXP SP3 Desktop 5.9 DVD?
• No, the WinXP SP3 Desktop 5.9 DVD should only be used in the following situations: • • To upgrade a Windows 2000 system to Windows XP. • To reinstall Windows XP Professional on a PC that has ceased to function correctly. • To install an operating system and the included Family History software on a donated PC.
