About Windows 11 Professional:
Windows 11, the first major Windows release since 2015, builds upon its predecessor by revamping the user interface to follow Microsoft's new Fluent Design guidelines.

That separation lets you spread several programs across the screen, sharing bits of information among them. The Windows 11 start menu is now loaded with more features and tools and it gives quick access to various tools and controls. Similarly, its security features help you to stay safe from various and malicious files. With powerful Windows defender and read-time scanning and monitoring, it offers the best security solutions and, in many cases, you don’t need to have an antivirus. In battery optimization, it offers the best solutions and enables you to stop, pause or terminate the background process.
The redesign, which focuses on ease of use and flexibility, comes alongside new productivity and social features and updates to security and accessibility, addressing some of the deficiencies of Windows 10.
