I want to do this! What's This?
It can be extremely tricky to remove Microsoft Office from the Windows Registry, so it should not be
attempted by an inexperienced user. Novice users should try using a registry cleaner instead of trying to
manually remove the registry keys. You might want to remove the registry keys for Microsoft Office if
the software did not fully uninstall properly. In that case, you will need to manually remove references
to the software in the registry.
