Windows 10 is an operating system developed by Microsoft as part of the Windows NT family. It was officially released to the public on July 29, 2015. Windows 10 is designed to run on personal computers, including desktops, laptops, and tablets. It introduced a new user interface that combines elements from both the traditional Windows desktop and the tile-based interface of Windows 8.

Key features of Windows 10 include the Start Menu, which was reintroduced with a mix of traditional application shortcuts and live tiles; improved virtual desktop support; the Cortana digital assistant; Microsoft Edge web browser; and enhanced security features like Windows Defender and Windows Hello. Windows 10 also supports Universal Windows Platform (UWP) apps, enabling applications to run across various device types.

Windows 10 follows a “Windows as a Service” model, meaning it receives regular updates that include safety patches, new features, and improvements over time. This approach aims to keep the OS up-to-date and secure without the need for entirely new versions, though major feature updates are released periodically. Windows 10 is widely used and supports a vast range of software and hardware, making it one of the most popular operating systems in use today.
