OneNote (part of Microsoft Office) is IMHO by far the best Note Programm for Windows, no GM should be without it, especially if you have a tablet-pc (handwriting in Session is awesome).
Inspiration Pad Pro is great Random-Table generator and it is free!
Also a PDF Reader should be installed and one of the countless DiceRollers (like mine Flanfs RPG Page Main/Flanf's Dice Roller
).
I also like Mindmapper-Programms when I create Adventures, but this is only for the preparation not for the actual session.
