Windows 11 features major changes to the Windows shell influenced by the canceled Windows 10X, including a redesigned Start menu, the replacement of its "live tiles" with a separate "Widgets" panel on the taskbar, the ability to create tiled sets of windows that can be minimized and restored from the taskbar as a group, and new gaming technologies inherited from Xbox Series X and Series S tels que Auto HDR et DirectStorage on compatible hardware. Internet Explorer (IE) has been replaced by the Chromium-Basé sur Microsoft Edge as the default web browser, like its predecessor, Windows 10et Microsoft Teams is integrated into the Windows shell. Microsoft also announced plans to allow more flexibility in software that can be distributed via the Microsoft Store and to support Android applications on Windows 11 (including a partnership with Amazon to make its app store available for the function).
Citing security considerations, the system requirements for Windows 11 were increased over Windows 10. Microsoft only officially supports the operating system on devices using an eighth-generation Intel Core CPU or newer (with some minor exceptions), a second-generation AMD Ryzen CPU or newer, or a Qualcomm Snapdragon 850 ARM system-on-chip or newer, with UEFI et Trusted Platform Module (TPM) 2.0 supported and enabled (although Microsoft may provide exceptions to the TPM 2.0 requirement for OEMs). While the OS can be installed on devices with unsupported processors, Microsoft does not guarantee the availability of updates. Windows 11 removed support for 32-bit x86 and 32-bit ARM CPUs and devices that use BIOS firmware.
Windows 11 has received a mostly positive reception. Pre-release coverage of the operating system focused on its stricter hardware requirements, with discussions over whether they were legitimately intended to improve the security of Windows or as a ploy to upsell customers to newer devices and over the e-waste associated with the changes. Upon release, it was praised for its improved visual design, window management, and stronger focus on security, but was criticized for various modifications to aspects of its user interface that were seen as worse than its predecessor; some were seen as an attempt to dissuade users from switching to competing applications.
As of March 2024[mise à jour], Windows 11, at 26% worldwide, is the second most popular Windows version in use, with its predecessor Windows 10 at 2.5 times the market share. Windows 11 has an estimated 19.75% share of all PCs (the rest being other Windows editions and other operating systems such as macOS et Linux), and an estimated 7.8% share of all devices (including mobile, tablet and console) are running Windows 11.
