Microsoft will soon release the source code and binaries for a Windows 7 tool that was recently found to contain code licensed under the GNU General Public License. The tool in question is the company’s free Windows 7 USB / DVD Download Tool, which enables consumers to create bootable USB drives or DVD backup media from the electronic software edition of Windows 7 that comes in an ISO format. “Within Windows” blogger Rafael Rivera Jr. uncovered the GPL-licensed code earlier this month.
