Windows: A Complete Guide to Microsoft's Operating System
Windows stands as the world's most widely used operating system, powering over 1.4 billion devices globally. Since its introduction in 1985, Microsoft's flagship software has evolved from a simple graphical interface to a sophisticated computing platform that manages hardware resources, runs applications, and provides essential services for both personal and professional use.
Key Features and Functionality
The Windows operating system includes essential features like file management, security protocols, and networking capabilities. The Start menu serves as the central hub for accessing applications, while File Explorer enables users to organize and manage their documents. Built-in security features include Windows Defender antivirus protection, firewall settings, and regular security updates to protect against emerging threats.
Windows Versions and Evolution
Microsoft regularly releases new versions of Windows, each bringing improvements in performance, security, and functionality. Windows 11, the latest version, introduces a centered taskbar, enhanced widgets, and improved touch capabilities. Previous versions like Windows 10, 8.1, and 7 established important foundations for modern computing, though older versions are no longer supported with security updates.

Modern Windows versions require specific hardware configurations to run effectively. Windows 11 demands more robust specifications, including a compatible 64-bit processor, TPM 2.0, and at least 4GB of RAM. Storage requirements typically start at 64GB, though more space is recommended for optimal performance and future updates.
