Microsoft Bob, launched in 1995 as a user interface to simplify computer navigation, sold only around 30,000 copies before being discontinued. In 2001, during the development of Windows XP, Microsoft included an encrypted version of Bob on the installation CDs to fill 30 MB of unused space and deter piracy. This decision was made to slow down users with dial-up connections attempting to illegally copy the operating system. The developer found floppy disk images of Microsoft Bob, encrypted them, and added them to the Windows XP CD, meaning that purchasers of Windows XP received a copy of this previously unsuccessful software.
