Windows 10 Insider Preview has been migrated from the iron branch to the cobalt branch

Microsoft has updated the Windows 10 Insider Preview version as planned during this period, but careful users should notice that the branch to which this version belongs has not been changed.

That is, these development versions are mainly based on the iron branch (FE_RELEASE), and the representative of the iron branch is based on the manganese branch is the Windows 10 21H1 version.

Since this version is a minor version and will be released soon, Microsoft needs to migrate to a new branch, so in today’s new version, the CO_RELEASE is coming.

The version of the cobalt branch is Windows 10 21H2, which is the Sun Valley version that we are very concerned about. This update is the main version that contains a lot of new features.

The switching of channels is actually not a major event, but it can let us know the progress of Microsoft’s development process, especially the Sun Valley version that we are very concerned about.

The new version this fall is a major version update of Windows 10. This version will make major adjustments to the user interface through a project called Sun Valley.

This will also be the new major version update after the Windows 10 20H1 version, and 20H2 and the upcoming 21H1 are both minor updates without much functionality.

Switching from the iron to the cobalt branch means that the new version of the fall will enter the main development process, and the subsequent development of new functions may increase and the speed of change will also increase.

Microsoft said that starting from this new version, the branch is switched, and the watermark in the lower right corner of the desktop and other places on the system will become the cobalt branch.

If nothing happens, Microsoft may release a minor update to Windows 10 21H1 from the end of this month to the beginning of next month. This version will be installed directly as a patch.

The major update in autumn is expected to arrive around October. In previous years, Microsoft will release the image file in early October for users.

Then Microsoft will start the push work and gradually provide new versions to all users, but the whole process will be very long and may not be completed until early next year.

If you are looking forward to the new features of the Sun Valley version, you might as well install the development test version on the virtual machine, because Microsoft has also released a new version of the image.
