There is a way to legitimately download licensed commercial software, free, with only a few strings attached. The website GiveAwayofTheDay makes available for download a fully licensed and legal version of a commercial software title each day, but only one title per day, and each title is only available for download for 24 hours. Once downloaded, the commercial software is usable for a typical license term, usually for a year or for whatever the normal duration of the license for that software title. Be sure to follow the included instructions to register and activate the software. While licensed and legal, this commercial software does not offer technical support or updates under the terms of the free license.
