Accounts with the "Perform volume maintenance tasks" user right can manage volume and disk configurations. This could be used to delete volumes, resulting in data loss or a denial of service.

Run "gpedit.msc".

Navigate to Local Computer Policy >> Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment.
