The Dev Channel is for highly technical users who love to be the first to see the latest features and updates for all things Windows. It will get builds that are earliest in a development cycle with the latest work-in-progress code from our engineers. These aren't always stable builds, and sometimes you will see issues that block key activities or require workarounds while flighting in this channel.
These builds aren't matched to a specific release, which means these may simply be the latest work-in-progress code from our engineers. New features and OS improvements in this channel will show up in future Windows releases when they're ready, and we may deliver them as full OS build updates or servicing releases. Your feedback here will help our engineers with major fixes and changes to the latest code.
You now need to assess if you are still wanting to be on the Dev channel.
