Disk Management utility that ships with Windows is primarily used to create and format hard disk partitions. In addition to that, you can use the Disk Management to shrink and extend partition size, change the drive letter of partitions, assign drive letter to partitions, and create, attach, & detach VHDs (virtual hard disks).
