In summary:
- PCWorld reports that Windows 11 still relies on code from the 1990s, particularly the Win32 API from Windows 95, for basic functions like right-clicking.
- Microsoft CTO Mark Russinovich acknowledges the unexpected longevity of this legacy code, which remains fundamental to many applications and core Windows operations.
- Previous attempts to modernize the Windows API, including WinRT, failed to fully replace the enduring Win32 system that continues powering today’s operating system.
