Specify timeout for fast user switching events This policy setting specifies the number of seconds a pending fast user switch event will remain active before the switch is initiated. By default, a fast user switch event is active for 10 seconds before becoming inactive. If you enable this policy setting, you can configure the fast user switch event timeout to specify the number of seconds the event remains active. This value cannot exceed 60 seconds. If you disable or do not configure this policy setting, a default value of 10 seconds is used for fast-user switch event timeouts.
