Synopsis

• Unconditionally reboot a Windows machine, wait for it to go down, come back up, and respond to commands.
• For non-Windows targets, use the :ref:`ansible.builtin.reboot <ansible.builtin.reboot_module>` module instead.

Parameters

Parameter	Choices/Defaults	Comments
boot_time_command string	Default: "(Get-CimInstance -ClassName Win32_OperatingSystem -Property LastBootUpTime).LastBootUpTime.ToFileTime()"	Command to run that returns a unique string indicating the last time the system was booted. Setting this to a command that has different output each time it is run will cause the task to fail.
connect_timeout float	Default: 5	Maximum seconds to wait for a single successful TCP connection to the WinRM endpoint before trying again. aliases: connect_timeout_sec
msg string	Default: "Reboot initiated by Ansible"	Message to display to users.
post_reboot_delay float	Default: 0	Seconds to wait after the reboot command was successful before attempting to validate the system rebooted successfully. This is useful if you want wait for something to settle despite your connection already working. aliases: post_reboot_delay_sec
pre_reboot_delay float	Default: 2	Seconds to wait before reboot. Passed as a parameter to the reboot command. The minimum version is 2 seconds and cannot be set lower. aliases: pre_reboot_delay_sec
reboot_timeout float	Default: 600	Maximum seconds to wait for machine to re-appear on the network and respond to a test command. This timeout is evaluated separately for both reboot verification and test command success so maximum clock time is actually twice this value. aliases: reboot_timeout_sec
test_command string		Command to expect success for to determine the machine is ready for management. By default this test command is a custom one to detect when the Windows Logon screen is up and ready to accept credentials. Using a custom command will replace this behaviour and just run the command specified.

Notes

Note

• If a shutdown was already scheduled on the system, :ref:`ansible.windows.win_reboot <ansible.windows.win_reboot_module>` will abort the scheduled shutdown and enforce its own shutdown.
• Beware that when :ref:`ansible.windows.win_reboot <ansible.windows.win_reboot_module>` returns, the Windows system may not have settled yet and some base services could be in limbo. This can result in unexpected behavior. Check the examples for ways to mitigate this. This has been slightly mitigated in the 1.6.0 release of ansible.windows but it is not guranteed to always wait until the logon prompt is shown.
• The connection user must have the SeRemoteShutdownPrivilege privilege enabled, see https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/force-shutdown-from-a-remote-system for more information.
• This module is equivalent to using the /f forced option for reboot on a windows host
