correct, i have found reference to them in my windows folder. so what do i do? delete them in the windows folder?

Yes, they are the backups for uninstalling a hotfix, however, that is highly recommended against. It won't do any harm to your system by removing them.

so what you're saying is that i could (and should) delete all those folders in C:\windows that begin with $NtUninstallKBxxxxxxx? as well as the $hf_mig$ folder? that they serve no purpose?

thx.

just one question... i had always thought, perhaps erroneously, that the MS windows update site checked those exact folders to see which updates one was lacking... if that is the case, then if i deleted all those folders it would report that i needed to install all those updates again. plz enlighten me about that if you can...

They do serve a purpose, that is to restore the Windows files to their previously non-updated versions. However, most people don't do that because you wouldn't want to undo a security fix for some sort of 0-day security flaw that "crap out there" is trying to exploit. Especially if you don't have any protection (firewall).

No, Windows Updates verifies that info with the .CAT files located in:

C:\WINDOWS\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE} <(the numbers and letters may be different for you)

just went to MS update after deleting all those files and folders... and the updates i had listed to install by the update site were still at zero KB. so i went to the CAT folder you mentioned and deleted the cat files with the KB numbers of those 0KB files on the update site. Just gone back to the MS update site to see what happens now...

still at zero....
