Uninstalling the 2007 Office Suites Windows Installer Cleanup Utility

Windows XP Professional, ver 2002, (9.0.6926) SP2 NTFS
Office 2000 Professional SP3
Internet Explorer 7.0.5730.11 128 bit cipher strength

Uninstalling the 2007 Office Suites. Even though I'm still using Office
2000 SP3, I have downloaded the Office 2007 files from Windows Updates as
they came along. I know they are located in Control Panel's System, but I
would say they are not installed files since they don't appear on the
Program Files menu. In regard to prepping for SP3, are they considered
"Installed" with the Microsoft Installer? When reviewing the files, it looks
to me that the only thing they are doing, is showing all the preinstalled
settings that will take effect when / if I actually install the 2007
Office. Is this correct?
