“Every year PCMag puts together a fresh look at the Best Free Software. We check the previous year’s picks to make sure they’ve still got the chops (and the $0 price tag) and cull through other options that have come our way. We concentrate on productivity apps and utilities for Windows users, but make note when a program also works for Mac OS X and Linux distributions. Every one of the products in this list that is classified as a Windows product is compatible with XP up to Windows 7—unless otherwise noted.”
