Just like the existing Disk Management Tool ( diskmgmt.msc), in the modern disk manager also you can change the drive letter. You can click the Change Label button, which will open a popup asking you to update the label of the volume. If you click a volume/partition of the disk, you will be allowed to see it's properties, change the label, drive letter, size and format the disk. As it is still in the early preview stage, and hidden behind a config change, the UI is not exactly what going to come next but will give you a brief of the changes coming up next. Once you navigate to the Manage Disks and Volumes page, you will find all the disks and drives listed on the page. If you are having Windows 10 build 20175 and higher, you can also access the new Disk Management Tool (which is currently hidden behind another config) by opening the Windows 10 Settings app and navigating to System | Storage | Manage Disks and Volumes as shown in the following screenshot: If you are on the Dev Channel, you can experience the current development progress prior to the final release. Windows 10 Insiders Preview build 20175 brings some new features to Windows and Microsoft Edge. Insiders having build 20175 can enable the option to preview the new disk manager.It is currently behind a hidden config.

Windows 10 is going to get a modern Disk Management tool.
