The difference between win10 and win11:
Windows 11 is a new operating system announced by Microsoft on June 24, 2021. Compared with Windows 10, it brings some significant changes in appearance, functionality, and performance. Below I will introduce the main differences between Windows 10 and Windows 11.
First of all, in terms of appearance, Windows 11 adopts a new interface design language called "Sun Valley". Compared with the tiled Start menu of Windows 10, Windows 11 introduces a center-aligned Start menu, while adding rounded corners and transparency effects to make the overall interface more modern and concise. The taskbar has also been resized, with icons and notification areas centered and resizable. In addition, the minimize, maximize and close buttons of the window have also been moved to the middle and upper part of the window, further improving user convenience.
Secondly, in terms of functionality, Windows 11 adds some new features. An important update is native support for Android apps, which users can download from the Microsoft Store and run on Windows 11. In addition, Windows 11 also strengthens support for touch and laptop computers, improves virtual desktop capabilities, and introduces new window management features called Snap Layouts and Snap Groups, making it easier for users to organize and manage multiple application windows. At the same time, Windows 11 also provides new gaming features, including DirectStorage technology and Auto HDR functionality, which improves gaming performance and experience.
Third, in terms of performance, Windows 11 introduces a series of optimizations to provide faster speeds and greater efficiency. It uses more advanced core technology and improves system resource management and power consumption control, thereby improving overall performance and battery life. In addition, Windows 11 also supports more hardware features, such as TPM 2.0 (Trusted Platform Module) and Secure Boot, to provide higher security and reliability in protecting user data.
