While I do take the time to look at General Information surrounding each Security Update
that Microsoft releases, a couple of news articles here and here that surfaced this
week (pertaining to the MS10-021 Security Update) made me go back and have a closer
look at the full Microsoft Security Bulletin details for MS10-021 here.

If you were to open the Frequently Asked Questions (FAQ) section (a section I honestly
don't take the time to read) sure enough, there is a general statement concerning the
prevention of the update from installing "if certain abnormal conditions exist on
32-bit systems".

So if you happened to be using WinXP and encountered an error while performing an Update
for MS10-021, Microsoft has provided a link here to officially explain what the
error means and what resolution steps can be taken.

Thanks to reader Angela for submitting the second news article referencing this condition.
