Must-have Windows utilities for 20 essential tasks

Alright, its Windows. I get that, but still lots of people use it on everyday basis (including me). But, if you don't have some "must-have" utilities, then your time on Windows is really going to hurt you. So, save that burn for some other time, and see this computer world article. It contains links to few quite useful but still open-source windows utilities, e.g. IrfanView (image viewing software), TrueCrypt (file encryption), FileZilla (FTP browser), CutePDF (PDF writer) etc.
