Windows 10 21H1 will be the eleventh major update expected to arrive sometime during spring 2021 with a new set of features and improvements.

At this time, all the enhancements are available through the Dev Channel. Windows 10 Dev Channel has been designed for “highly technical users.” When using this channel from the Windows Insider Program, you’ll receive builds that are rough and contain code that is still in development. These builds won’t be stable, you’ll come across errors and problems, and you may have to resource to workarounds that may affect your experience.

Previews on the Dev Channel are not attached to any specific release of Windows 10. Instead, the features and changes in this channel will appear in future releases when they’re ready, and not necessarily in the Windows 10 21H1 update.
