Privileges are granted by default. The user/group is granted only the privileges specified by the `Privilege` property. All other privileges are revoked. To revoke *all* a user's privileges, set the `Ensure` property to `Absent`. To revoke specific privileges, grant the user just the desired privileges. All others are revoked. *Privilege names are **case-sensitive**.* Valid privileges are documented on Microsoft's website: [Privilege Constants](http://msdn.microsoft.com/en-us/library/windows/desktop/bb530716.aspx) and [Account Right Constants](http://msdn.microsoft.com/en-us/library/windows/desktop/bb545671.aspx). Here is the most current list, as of August 2014: * SeAssignPrimaryTokenPrivilege * SeAuditPrivilege * SeBackupPrivilege * SeBatchLogonRight * SeChangeNotifyPrivilege * SeCreateGlobalPrivilege * SeCreatePagefilePrivilege * SeCreatePermanentPrivilege * SeCreateSymbolicLinkPrivilege * SeCreateTokenPrivilege * SeDebugPrivilege * SeDenyBatchLogonRight * SeDenyInteractiveLogonRight * SeDenyNetworkLogonRight * SeDenyRemoteInteractiveLogonRight * SeDenyServiceLogonRight * SeEnableDelegationPrivilege * SeImpersonatePrivilege * SeIncreaseBasePriorityPrivilege * SeIncreaseQuotaPrivilege * SeIncreaseWorkingSetPrivilege * SeInteractiveLogonRight * SeLoadDriverPrivilege * SeLockMemoryPrivilege * SeMachineAccountPrivilege * SeManageVolumePrivilege * SeNetworkLogonRight * SeProfileSingleProcessPrivilege * SeRelabelPrivilege * SeRemoteInteractiveLogonRight * SeRemoteShutdownPrivilege * SeRestorePrivilege * SeSecurityPrivilege * SeServiceLogonRight * SeShutdownPrivilege * SeSyncAgentPrivilege * SeSystemEnvironmentPrivilege * SeSystemProfilePrivilege * SeSystemtimePrivilege * SeTakeOwnershipPrivilege * SeTcbPrivilege * SeTimeZonePrivilege * SeTrustedCredManAccessPrivilege * SeUndockPrivilege * SeUnsolicitedInputPrivilege `Carbon_Privilege` is new in Carbon 2.0. .LINK Get-Privilege .LINK Grant-Privilege .LINK Revoke-Privilege .LINK Test-Privilege .LINK http://msdn.microsoft.com/en-us/library/windows/desktop/bb530716.aspx .LINK http://msdn.microsoft.com/en-us/library/windows/desktop/bb545671.aspx .EXAMPLE > Demonstrates how to grant a service user the ability to log in as a service.
