FYI: Download free Wise Disk Cleaner. I've been using it for years, and it apparently does this and more. I usually clean up over a GB after a clean install. Just click on the "Slimming System" tab, and check the box "Windows Installer Baseline Cache". You can also remove language packs like the Chinese and Japanese as well as sample media files.
Yeah you can save the search as a virtual folder or whatever too... then just open it and delete the contents.
Also I think both of these have custom options for deleting Mac shit.
