Windows 11 is a major release of the Windows NT operating system and is the successor to Windows 10. It introduces new features such as a redesigned interface, new productivity and social features, and updates to security and accessibility, along with improvements to performance.^[1][2][3]

Windows shell

• Fluent Design System: Updates to the Fluent Design System, a design language introduced by Microsoft in 2017,^[4] are featured in Windows 11. According to Microsoft, the design of Windows 11 is "effortless, calm, personal, familiar, complete, and coherent."^[5] The redesign focuses on simplicity, ease of use, and flexibility,^[1] addressing some of the deficiencies of Windows 10.^[3] Most interfaces in Windows 11 feature rounded geometry, refreshed iconography, new typography, and a refreshed color palette. In addition, translucency and shadows are made more prevalent throughout the system.^[6] Windows 11 also introduces "Mica", a new opaque Material that is tinted with the color of the desktop wallpaper.^[7][8]
• Start Menu: The Start menu has been significantly redesigned in Windows 11, adhering to the principles of the updated Fluent Design System. The menu has now been moved to the center by default, with an option to move it back to the left side. The Live Tiles feature introduced in Windows 8 is replaced by a set of pinned apps and a new cloud-powered "Recommended" section that shows recently opened files and documents from any location, including a PC, a smartphone, and OneDrive. The new Start menu also includes a search box.
• Taskbar: The Taskbar has also been center-aligned, and now includes new animations for pinning, rearranging, minimizing, and switching apps on the Taskbar.^[9] The buttons can still be moved to the left-hand corner as in Windows 10.
• Notification Center & Quick Settings: The Action Center from Windows 10 has been replaced by a Notification Center and a Quick Settings menu, both accessible from the lower-right corner of the Taskbar. The Notification Center contains all the user's notifications and a full-month calendar, while the Quick Settings menu lets the user manage common PC settings quickly and easily like Volume, Brightness, Wi-Fi, Bluetooth, and Focus Assist. Directly above the Quick Settings menu, the user can see media playback information when watching a video on platforms such as YouTube, or when listening to music in apps like Spotify.
• File Explorer: The File Explorer on Windows 11 has been refreshed with the Fluent Design System and the Ribbon interface has been replaced with a new command bar with a revamped user interface and a Mica background. It also introduces revamped context menus with rounded corners, larger text, and Acrylic. App developers will also be able to extend the new context menus.
• Themes: In addition to new default themes on Windows 11 for both Light and Dark mode, it also includes four new additional themes. Windows 11 also adds new high-contrast themes for people with visual impairments.
• Sounds: Windows 11 introduces a new set of system sounds. The sounds are slightly different depending on whether the theme is set to light or dark mode. In addition, a new Windows startup sound replaces the one used since Windows Vista.
• Widgets: Windows 11 adds a new taskbar flyout named "Widgets", which displays a panel with Microsoft Start, a news aggregator with personalized stories and content (expanding upon the "news and interests" panel introduced in later builds of Windows 10). The user can customize the panel by adding or removing widgets, rearranging, resizing, and personalizing the content.

User Interface (UI) improvements

• Windows 11 updates several system dialog boxes such as the alert for when the battery is running low.
• The taskbar previews have been updated to reflect Windows 11's new visual design.
• The hidden icons flyout on the lower-right corner of the taskbar has also been redesigned to match Windows 11's visuals.

Multitasking

• Snap layouts: Users can now hover over a window's maximize button to view available snap layouts, and then click a zone to snap the window. They will then be guided to snap windows to the rest of the zones within the layout using a guided snap assist. There is a set of four available snap layouts on smaller screens.
• Snap groups: Snap groups are a way to easily switch back to a set of snapped windows, which are stored in the grouped app's taskbar icons.
• Virtual desktops: Virtual desktops can be accessed via the Task View feature on the Taskbar. Users can reorder and customize the background for each of their desktops. They can also hover over the Task View button on the Taskbar to quickly access their desktops or to create a new one.
• Docking: When the user undocks a laptop, the windows on the monitor will be minimized, and when the laptop is redocked to a monitor, Windows will put everything where it was before.

Input

• Touch keyboard: Windows 11 introduces thirteen new themes to customize the touch keyboard, including 3 hardware-matching themes that match the Surface keyboard colors. It also adds a new theme engine that allows the user to create a custom theme using background images. In addition, Windows 11 adds the ability to resize the touch keyboard.
• Voice typing: Windows 11 includes a new voice typing launcher to easily start voice typing in a selected field. It is turned off by default, but it can be turned on in Settings and placed in any area of the screen.

New and improved gestures can be used on tablets and touchscreens.^[2][11] App windows now have larger touch targets and will automatically arrange themselves in split view when the screen is rotated. Windows 11 seems to be optimized for desktops and tablets without combining the two like Windows 8 and Windows 10 did.
• Pen menu: For digital pen users, a new pen menu has been added, which is accessible by clicking the pen icon on the taskbar. By default, it contains two apps that can be customized by clicking the gear icon and selecting "Edit pen menu". In the flyout, users can add up to four of their favorite drawing or writing apps to the pen menu to open them quickly when using a pen.
• Language and input switcher: A switcher that will show up next to the Quick Settings menu allows the user to switch languages and keyboard layouts. Users can press the Windows + Spacebar keyboard shortcut to toggle between input methods.

Windows 11 allows users to install and run Android apps on their devices using the new Windows Subsystem for Android (WSA) and the Android Open Source Project (AOSP). This runs with Intel Bridge Technology, a runtime post-compiler that enables apps written for other architectures to run on x86.^[13][14] These apps can be obtained from the Microsoft Store via the Amazon Appstore,^{[15][16][17][18]} or through other sources.^[19]

It has a left-handed navigation that persists between pages, and it adds breadcrumbs as the user navigates deeper into the settings to help them know where they are and to not get lost. The Settings app also includes brand new pages, with new controls at the top that highlight key information and frequently used settings for the user to adjust to their content. These new controls span across several category pages like System, Bluetooth & devices, Personalization, Accounts and Windows Update. It also adds expandable boxes for pages with many settings.
• Snipping Tool: In Windows 11, both the legacy Snipping Tool and newer Snip & Sketch apps have been replaced by a new Snipping Tool app with the combined functionality of both apps.

Windows 11 also introduces a new Settings page for the Snipping Tool. In addition, the new Snipping Tool adds support for dark mode.

The Photos app also introduces a floating menu with new editing controls and will let users compare up to four pictures at once.

System security and performance

Microsoft promoted performance improvements such as smaller update sizes, faster web browsing in "any browser", faster wake time from sleep mode, and faster Windows Hello authentication.^[2][36]

As part of the minimum system requirements, Windows 11 only officially supports devices with a Trusted Platform Module 2.0 security coprocessor.^[37][38] According to Microsoft, TPM 2.0 is a "critical building block" for protection against firmware and hardware attacks. In addition, Microsoft now requires devices with Windows 11 to include Virtualization-Based Security (VBS), Hypervisor-Protected Code Integrity (HVCI), and Secure Boot built-in and enabled by default.^[39] The operating system also features hardware-enforced stack protection for supported Intel and AMD processors for protection against zero-day exploits. Windows 11 Home SKUs require an Internet connection and a Microsoft account for first-time setup.^[10]
