From one of our newsletters, WXPnews:
Did you know that there is a “toolbox” full of XP utilities that aren’t installed on your computer by default, but are available on the installation CD? These include tools to provide information about the encrypting file system, directory disk usage, network connectivity and more. The Windows Installer Cleanup Utility removes old installation configuration information that can interfere with reinstalling a software product. The Memory Profiling Tool takes a snapshot of the system and records details of the memory resources being used by the system in a log file. For more information about the support tools and how to install them from the installation CD, click here.
