A new Windows 10 Insider Preview build adds a new disk management interface to Settings for those in the Dev channel, so this is probably aimed for Windows 10 version 21H1 or later.

Windows 10 Insider Preview build 20197 comes with exactly one new feature: A new Manage Disk and Volumes page in Settings > System > Storage > Manage Disks and Volumes that duplicates some of the functionality of the old Disk Management MMC (Microsoft Management Console) that will still be available for us old-timers.

The new interface provides a way to view information about each disk attached to the PC, create and format volumes, and assign drive letters. Microsoft claims it was “built from the ground up to with accessibility in mind,” whatever that means, and it offers better integration with Storage Spaces.

That’s it for new features.
