Windows 11 has been released as a free upgrade for compatible laptops and desktop computers running Windows 10 with a slew of new features and changes. On October 5, 2021, Microsoft has begun the slow rollout starting with newer devices first. Then, it will expand to more compatible computers over time, and it will become fully available by mid-2022.
As part of the new experience, Windows 11 introduces a new interface that uses a modern design language with rounded corners and new materials like Mica, an element that lets the background shine through without impacting performance or battery life and falls back to a solid color when the app is not in focus.
In this version, you will also find a redesigned Start menu and Taskbar that are now aligned to the center of the screen, and there are some new features, such as Snap layouts, Chat from Microsoft Teams, Widgets, and new multiple displays improvements. Furthermore, Windows 11 ships with many overhauled experiences like the new out-of-box experience (OOBE), Settings, Desktops, Notification Center and Quick Settings that replace the Action Center experience. And there are updates for many built-in apps, such as File Explorer, Calculator, Microsoft Paint, Clock, and many more.
Since Windows 11 will coexist with Windows 10 for at least a few more years, the new version has been offered as a completely optional upgrade that you must trigger manually using at least one of the supported methods, including Windows Update, and Installation Assistant, or ISO file. (Starting with this release, the Media Creation Tool no longer offers the option to perform an in-place upgrade.)
In this Windows 11 guide, we will walk you through the steps to download and install Windows 11 on your desktop, laptop, or tablet.

Anyone else getting 0xa0000400 error?
I get a bluescreen during the installation (after the download is completed). And the PC restarts undoing the changes, reverting back to Windows 10. Installing on a custom built ryzen 2600x with 24 gb ram (TPM 2.0 and secure boot enabled already)!
I tried again after clearing the software distributon folder, and now it works well!
My Surface Pro X is eligible for Windows 11 but none of the mentioned tools in the article works. The update assistant does not work for Arm devices and if I try to download W11 on a USB pen it seems that you can just get Windows 11 for X86 devices and not Arm, unless I am making some mistakes
