Software Role Play: PC Makers’ Licensing Tricks Exposed
updated June 24, 2025
New PCs frequently enough come with pre-installed software, sometimes activating into full versions at no extra cost. This perk stems from licensing agreements between PC manufacturers and software companies. Though, in the early days, some manufacturers attempted to circumvent this process.
During the Windows 95 era, as the “Plug and Play” specification was being developed, the operating system team sought ways to identify pre-specification PCs. One method involved searching the BIOS for copyright strings and firmware dates.
This investigation uncovered an unusual copyright string, ”Not Copyright Fabrikam Computer,” on a PC made by Contoso. Both names are fictional, used to illustrate the scenario without revealing the actual manufacturers involved.
Microsoft engineer Raymond Chen detailed in a blog post how Contoso, lacking an official license, aimed to activate the full software version on its PCs.To avoid licensing fees,the company added “Copyright Contoso Not Copyright Fabrikam Computer” to its copyright string. The trial software, searching for “Copyright Fabrikam Computer,” found it within the substring, inadvertently triggering full activation.
While more secure methods have since been implemented, this historical example highlights the lengths to which some original equipment manufacturers (OEMs) would go to distribute software without proper authorization. The role of ingenuity, however misguided, is clear.
What’s next
Future software licensing models will likely continue to evolve, incorporating more robust security measures to prevent similar bypasses. The industry will likely see a greater emphasis on digital rights management and secure boot processes.
