A definite yes to faststone - it is in my opinion definitely the best photo managing and minor editing tool that I have found (and I have looked a lot). I have shared with with a lot of people and they are all delighted by it.
Also :-
openoffice
firefox
thunderbird
For PHotography :-
gimp (DEFINITELY)
autostich for panoramas
qtpfsgui for HDR
and I have just discovered a really cool screen saver which shows you your photos or flikr photo! 3D Screensaver or the Photo!3D album
Also
Photostory3 for putting audio visuals of your photos together, lets you add text, change the transformation of one photo to the next and then add your own music or their music.
Thats all for now
