    User Account Control: Switch to the secure desktop when prompting for elevation

  • You use a standard user account to log on to the computer. This standard user account belongs to specific groups that have some administrative privileges. For example, the account belongs to the Backup Operators group, to the Network Configuration Operators group, or to the Power Users group.

  • You request remote assistance from an administrator.

  • The administrator creates a Remote Assistance session on the computer.
