After a desktop pool is created, you can customize, modify, or test individual machines by placing them in maintenance mode. When a machine is in maintenance mode, users cannot access the virtual-machine desktop.

You place existing machines in maintenance mode one at a time. You can remove multiple machines from maintenance mode in one operation.

When you create a desktop pool, you can start all the machines in the pool in maintenance mode if you specify machine names manually.


  1. In Horizon Console, select Inventory > Machines.
  2. Select a machine.
  3. Select Enter Maintenance Mode from the More Commands drop-down menu.
  4. Customize, modify, or test the virtual-machine desktop.
  5. Repeat Step 2 through Step 4 for all virtual machines that you want to customize.
  6. Select the customized machines and select Exit Maintenance Mode from the More Commands drop-down menu.


The modified virtual-machine desktops are available to users.
