I have just gone through our software share, tiding up old versions of acrobat reader, flash, promethean etc

This got me thinking, is there a freeware program that could create a menu listing for all the software installers in alphabetical lists. Like CD Autorun menus used to be - where an item was greyed out if it was already installed. Filtering the list by location or type of computer would be useful.

Does such a thing exist?
I did a quick google search which found several possibilities, but I thought you guys could save me some time if you already have one up and working.
