Microsoft has released ump{*filter*} number of IE versions.
http://www.*-*-*.com/ ;EN-US;q164539&
For e.g..
Version 5.50.4807.2300   Internet Explorer 5.5 Service Pack 2
Version 6.00.2600.0000   Internet Explorer 6
Version 6.00.2800.1106   Internet Explorer 6 Service Pack 1

I need to determine the service pack of IE on a system.To do this I maintain
a property file in
my application holding the mapping of various IE versions to their
corresponding servicepacks.
(I read the version of IE from registry entry
HKLM\Software\Microsoft\InternetExplorer  - Version subkey)

My problem is that the property file needs to be UPDATED EVERY TIME
Microsoft launches a new version of IE.
Is there some API or some other way to determine version of  IE SP on a
system without updating the property file?

Thanks.
