The Timeout for fast user switching events machine setting should be configured correctly. 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, the default value of 10 seconds will be used for fast-user switch event timeouts. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Biometrics\Timeout for fast user switching events (2) KEY: HKLM\SOFTWARE\Policies\Microsoft\Biometrics\Credential Provider\SwitchTimeoutInSeconds
