What is Windows
Windows is a widely used operating system (OS) developed by Microsoft Corporation that controls the overall functioning of a computer system and provides a user-friendly graphical interface for interacting with hardware and software. It acts as an intermediary between the user and the computer’s physical components such as the processor (CPU), memory (RAM), storage devices (hard disk or SSD), keyboard, mouse, monitor, printer, and network devices. Without Windows or any operating system, a computer cannot perform meaningful tasks because the hardware alone cannot understand user commands. Windows makes it possible for users to run application programs, manage files and folders, connect to the internet, and use different devices smoothly and efficiently.
Windows provides a Graphical User Interface (GUI) that allows users to work with icons, menus, buttons, and windows instead of typing complex commands. This interface includes important elements such as the Desktop, Start Menu, Taskbar, and File Explorer, which help users easily access programs and organize their data. Through File Explorer, users can create, copy, move, rename, and delete files and folders. The Start Menu helps launch applications, search for files, and access system settings. This visual and interactive environment makes Windows suitable for beginners as well as professional users in offices, schools, and industries.
One of the main responsibilities of Windows is resource management. It manages system resources such as CPU time, memory, and storage so that multiple programs can run at the same time without conflicts. This ability is called multitasking, which allows users to open a web browser, play music, and work on a document simultaneously. Windows also manages hardware through device drivers, which are special programs that allow the operating system to communicate with devices like printers, scanners, webcams, speakers, and USB drives. When new hardware is connected, Windows usually detects it automatically and installs the required drivers.
Windows also plays an important role in security and user management. It provides features such as user accounts, passwords, file permissions, and login systems to protect personal data. Built-in tools like Windows Defender, firewall, and regular security updates help protect the system from viruses, malware, and cyber threats. Windows Update keeps the operating system secure and stable by fixing bugs and improving performance. These security features make Windows reliable for both personal and business use.
Another key function of Windows is software support. It supports a huge variety of application software including word processors (Microsoft Word), spreadsheets (Excel), presentation tools (PowerPoint), web browsers (Edge, Chrome), multimedia players, graphic design software, programming tools, and games. Because of this wide software compatibility, Windows is the most popular operating system in homes, offices, educational institutions, and corporate environments. It also supports networking, allowing computers to connect to local networks and the internet for sharing data and communication.
Over time, Microsoft has released many versions of Windows such as Windows XP, Windows 7, Windows 8, Windows 10, and Windows 11, each improving performance, security, and user experience. Modern versions of Windows support touch screens, cloud services, virtual desktops, and advanced hardware like solid-state drives and high-resolution displays. Windows continues to evolve with new features to meet the needs of modern computing.
In conclusion, Windows is a powerful and user-friendly operating system developed by Microsoft that manages computer hardware, runs application software, provides security, and offers an easy graphical interface for users. It is essential for performing everyday computing tasks such as creating documents, browsing the internet, watching videos, playing games, and communicating with others. Due to its simplicity, flexibility, and wide compatibility, Windows remains one of the most important and widely used operating systems in the world.

Microsoft Owner
Microsoft Corporation is not owned by a single person. It is a public company, which means it is owned by shareholders around the world. However, it was founded by Bill Gates and Paul Allen, and today it is led by a professional management team.
Microsoft Corporation was founded on April 4, 1975, by Bill Gates and Paul Allen, who are widely recognized as the original owners and creators of the company. In its early years, Microsoft was privately owned and fully controlled by its founders, with Bill Gates playing the central role in shaping the company’s vision, developing its first software products, and expanding its business in the growing personal computer market. Over time, as Microsoft became more successful, the company was transformed into a public corporation in 1986 through an Initial Public Offering (IPO). After this, ownership of Microsoft was no longer limited to one or two individuals but was divided among millions of shareholders who purchased company stock.
Today, Microsoft does not have a single owner. Instead, it is owned by a large number of individual and institutional shareholders around the world. Major investment companies such as Vanguard Group, BlackRock, and State Street Corporation hold significant portions of Microsoft shares on behalf of their clients. Bill Gates, although no longer actively managing the company, still owns a small percentage of Microsoft shares and remains one of its most well-known stakeholders. However, he stepped away from day-to-day operations and leadership roles to focus on philanthropic work through the Bill & Melinda Gates Foundation. This shift marked the transition of Microsoft from being founder-led to professionally managed.
The daily operations and strategic direction of Microsoft are now guided by its executive leadership team rather than its founders. The current Chief Executive Officer (CEO) of Microsoft is Satya Nadella, who has held this position since 2014. Under his leadership, Microsoft has grown rapidly in areas such as cloud computing (Azure), artificial intelligence, and enterprise services. Satya Nadella also serves as the Chairman of the Board, meaning he plays a key role in both management and corporate governance. The Board of Directors represents the interests of shareholders and ensures that the company is run responsibly and profitably.
In conclusion, while Bill Gates and Paul Allen were the original owners of Microsoft, the company is now a publicly owned corporation with millions of shareholders worldwide. Microsoft is not owned by a single person but is controlled through a combination of shareholder ownership and professional management. The leadership of Satya Nadella has helped modernize the company and expand its influence in cloud technology, artificial intelligence, and global business services. This ownership structure reflects Microsoft’s transformation from a small startup founded by two programmers into one of the largest and most valuable technology companies in the world.
Short Answer (Exam Style)
Microsoft was founded by Bill Gates and Paul Allen in 1975. It is now a public company owned by shareholders. The current CEO of Microsoft is Satya Nadella.
