WinLock by Crystal Office Systems is an administrative security and access-control software designed to lock down specific Windows operating system functions, restrict user behavior, and protect sensitive files. It is widely deployed on public access computers, kiosks, educational systems, and shared household PCs to prevent unauthorized configuration modifications. Key Security Features
