The correct answer is C. Windows 11.
Windows 11 is the latest version of Microsoft Windows, a series of operating systems produced by Microsoft for personal computers, home computers, and mobile devices. It is the successor to Windows 10 and was released to manufacturing on October 20, 2021, and released to the general public on October 5, 2021.
Windows 11 is a major release of the Windows NT operating system family, succeeding Windows 10. It was announced by Microsoft on June 24, 2021, at its annual Build developer conference, and was released to the general public on October 5, 2021. Windows 11 is the first major version of Windows released since Windows 10 in 2015.
Windows 11 is a significant upgrade from Windows 10, with a new user interface, new features, and improved performance. The new user interface is designed to be more user-friendly and intuitive, with a focus on simplicity and ease of use. The new features include a redesigned Start menu, a new taskbar, and a new notification center. Windows 11 also includes improved performance and security.
Windows 11 is a free upgrade for eligible Windows 10 users. To upgrade, users must have a compatible device and must install the Windows 11 Insider Preview build. The Windows 11 Insider Preview build is a beta version of Windows 11 that is available to Windows Insiders. Windows Insiders are a group of users who volunteer to test new versions of Windows before they are released to the general public.
Windows 11 has been met with mixed reviews. Some users have praised the new user interface and features, while others have criticized the changes and the requirement for a compatible device. Windows 11 is still in its early stages of development, and it is likely that some of the changes will be made before the final release.
