Windows 11 relies on the Win32 API, a legacy system dating back to Windows 95, for core functionalities like right-clicking and launching applications. Microsoft’s Chief Technology Officer, Mark Russinovich, noted that the continued relevance of Win32 was unexpected, as few anticipated it would still be a primary interface in 2026. Despite attempts to modernize the Windows API with initiatives like WinRT, Win32 remains integral to many Windows operations. The separation between Win32 applications and web technologies has complicated the transition to a new API framework. Additionally, tools from Microsoft's past, such as Sysinternals, Sysmon, and ZoomIt, continue to play important roles in Windows management.
