DeleteKeyProtectors method of the Win32_EncryptableVolume class

The DeleteKeyProtectors method of the Win32_EncryptableVolume class deletes all key protectors for the volume.

If an unencrypted volume has key protectors, when DeleteKeyProtectors is run successfully the volume reverts to a standard NTFS file system.
