In SystemInformation[], one gets the "Release ID" as well as the "Creation Date".

I just installed Windows version:

Release ID (3868239, 3824638)
Creation Date Tue 20 Nov 2012 10:45:14

This was from an installer downloaded from the Wolfram User Portal
yesterday that, I presume, is the corrected version (with the fix about
previous-version faulty fonts).

Previously, I installed the Mac OS X version:

Release ID (3825048, 3824632)
Creation Date Tue 20 Nov 2012 10:31:01

Same Creation Date (except for a 150minute difference) between the two

So how could one tell from SystemInformation whether the Windows version
is in fact the latest?
