How to change file/s icons in addition to folder & shortcut icons ???

Can change folder and shortcut icons with XP features, but is there an XP feature or 3rd party software package (possibly freeware) that can change (all extension types) file icons ?
Am looking at shareware (about $20) 'IconChanger 3.7' but not sure what file extensions it can work with (have emailed IC tech support for that list, but have not yet heard back).
Any ideas ?

 

I've found a couple of free ones. There's the XP Transformation Pack which will make XP look like Vista (I think). I have another one, but I can't remember what it's called or where I downloaded it from. I think I have the info at home (I'm at work right know) and if I find it, I'll be sure to post it...

Edit: here's one I found whilst Googling. It's an icon pack for about 30 or 40 different extensions....
http://interfacelift.com/icons-win/details.php?id=1928 Their home page provides access to a bunch of other icons... check it out.. If you're interested in making your own icons, there's lots of tools out there. The free ones are OK but usually limited in features. IconCool is one of the better ones, but it's not free. I Googled "XP icons" and found lots of stuff...

Edit #2: if you have seen icons already on your PC that you'd like to extract for personal use, use IconSnatcher. It will look inside EXE files and DLL files (and lots of others) http://www.snapfiles.com/get/iconsnatcher.html
