You just need to right click the volume that you want to perform any task and then it will show all options that you can select. Sometimes, you may need to shrink volume on Windows 10 in order to resolve low disk space problem. However, the "Shrink Volume" option might become grayed out sometimes.

Sometimes, you may want to format disk volume on Windows 10 due to this or that kind of reason. Usually, you can format any volume on Windows 10 in "My Computer", but sometimes Windows will fail to complete the format. In this situation, somebody would like to open Disk Management to check if it is possible to complete the format there. However, the problem is that the "Format" option is grayed out. Here are some possible reasons why you meet the problem that Windows 10 Disk Management "Format" option is grayed out:
1. You select C drive (system partition) to format. Usually, you are not allowed to format C drive on all Windows operating systems including Windows 10 unless you reinstall the OS. Therefore, the "Format" option will stop working when you right click C drive under Windows 10 Disk Management.
2. The selected volume is corrupted due to virus infection or it contains too bad sectors. Sometimes, Windows 10 was unable to format a volume that has bad sectors, so the "Format" option shows grayed out on Windows 10 Disk Management.

Since Windows 10 operating system is installed on C drive, it will cause system corruption if you delete C drive. Windows system stops you from deleting or formatting C drive in order to keep your computer run normally.
