This is annoying: Sometimes an installation goes haywire and whenever you reboot your computer or run a particular application you get the Microsoft Office installation message asking you to insert a CD. Even after running Cleanup and clearing out the Windows cache you still get the install message.

One way to clean this up is the Installation Cleanup Utility. You can find it here:

This program works great on Office installs and just about any other installation.
