Begin to Preview Windows
First, make sure your device is ready to Preview Windows:
To install Windows Insider Preview Builds [1], you must be running a licensed version of Windows on your device. You can install Windows 11 here. If you're having issues installing Windows, you can also download a Windows Insider Preview ISO to get started.
The process of setting up your device to start running Insider Preview builds restarts your device during program setup and updating. Make sure you're ready for this, so you don't lose open documents or unsaved work. You might also want to take a picture of these directions or bookmark this page on your browser to get back to it easily. Make sure that we support your language.
