Abstract The release of Windows 11 in 2021, with its stringent TPM 2.0 and Secure Boot requirements, alienated millions of PC users. In response, a niche underground community began producing "Windows 11 Bootlegs"—heavily modified, unofficial ISO distributions. This paper examines the bootleg ecosystem as a socio-technical phenomenon, exploring its origins in the Windows XP/Vista era, its current manifestations, the aesthetic and functional modifications applied, and the severe security implications. We argue that bootleg OSes function as both a form of digital resistance against planned obsolescence and a dangerous vector for malware propagation. 1. Introduction A "bootleg" operating system is not merely a pirated copy of Windows; it is a customized, repackaged, and often pre-activated derivative. Unlike standard pirated ISOs (which simply bypass activation), bootlegs intentionally alter the OS's visual identity, remove core components (e.g., Windows Defender, Edge, Update services), and integrate third-party software, themes, and registry tweaks.
