1 Introduction
Poweroff is a small program that allows you to control the power state of your pc.
It can power off, shutdown or reboot your pc, log you off, lock your workstation, go to standby or hibernation mode and even wake up another pc.
All actions can be done locally or on a remote pc (if they are running poweroff).
The action can be performed immediately or scheduled, by using a built-in scheduler.
All actions and options can be controlled by command line options. This way, you can easily integrate poweroff in your batch files.
It should run on Windows 95/98/Me/NT4.0/2000/XP, each with its own limitations. Beware that I haven’t tested the program on these operating systems, but in theory it should work on all of them…
Since this release has been completely rewritten from scratch, it may be possible that it still contains some bugs. Please let me know if you find one.
Full source code is included!
2 Installation
Installation is very easy, just extract the poweroff.exe file somewhere where you can find it and double-click the executable. You do not need any of the other files in the zip file, unless you are interested in the source code.
To uninstall, simply delete the poweroff.exe file. Poweroff stores its settings in the registry, so you should remove them also, either by selecting ‘Remove settings’ from the file menu or by manually removing them from the registry using ‘regedit.exe’
(WARNING: using regedit can damage your Windows configuration, so be careful what you do!). The key that you can safely delete is
HKEY_CURRENT_USER\SOFTWARE\Poweroff
When poweroff starts up, it first looks for settings in HKEY_CURRENT_USER. If it cannot find any, then it looks in HKEY_LOCAL_MACHINE. This way you can define global settings and per user settings. You will have to create the global settings manually.
To delete the poweroff service, choose ‘Remove service’ from the service menu. The settings are automatically removed. To manually remove the service settings, delete the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Poweroff\Parameters
Other registry keys that may be lying around then the service is removed are:

HKEY_LOCAL_MACHINE \System\ControlSet00x\Services\PowerOff
HKEY_LOCAL_MACHINE \System\ControlSet00x\Enum\Root\LEGACY_POWEROFF
HKEY_LOCAL_MACHINE \System\ControlSet00x\Enum\Root\LEGACY_POWEROFF
These should disappear when your computer is rebooted. They can be safely deleted when the service is removed.
You need Internet Explorer 4.0 or higher because it uses some common controls that are shipped with IE.

3 Usage
3.1 Starting
When you double-click the poweroff executable, the main window is shown. Here you can select which action to perform and select the appropriate options. To execute the desired action, simply hit the ‘Do it’ button.
Figure 1
3.2 Actions
Poweroff supports the following actions:
3.2.1 Logoff
Logs off the current logged on user.
3.2.2 Reboot
Reboots the computer.
3.2.3 Shutdown
Shutdown the computer.
In NT/2000/XP this will display the standard message ‘It is safe to shutdown you computer’.
In Win9x/Me this will poweroff your pc if your hardware supports it
In NT/2000/XP this will display the standard message ‘It is safe to shutdown you computer’.
In Win9x/Me this will poweroff your pc if your hardware supports it
3.2.4 Poweroff
This action will physically power off your computer. Your hardware must support this, for example an ATX motherboard and power supply should support it, but an old AT motherboard probably doesn’t support it. You also have to have ACPI or APM enabled in your bios. And the power options must be correctly configured in the Windows control panel. If Windows performs a poweroff when you do a normal Windows shutdown from the start menu, then it will also work with this program.
To enable poweroff in Windows NT, you will need a hal.dll that is capable of shutting down your workstation. You can try one that's supplied with service pack 4 (or higher): hal.dll.softex
Just extract the service pack (with the /x option),
There are several machine-specific HAL.DLL’s, and you MUST extract the matching HAL*.DLL.SOFTEX from the service pack. To avoid problems when someone overwrites the good HAL.DLL with a bad one it's better to rename HAL*.DLL.SOFTEX to %SystemRoot%\System32\HALPOWER.DLL for instance, copy the line in %SystemDrive%\BOOT.INI which loads the current system, alter the description and append " /HAL=HALPOWER.DLL". Now one can choose between the two HALs and has a fallback if the new one fails.

If you like NT to automatically poweroff at shutdown, set the following registry key to 1: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\PowerdownAfterShutdown
3.2.5 Standby
If your pc supports it, then this will put your pc into standby mode (sleep mode). If you get a strange error message, then probably one of your device drivers doesn’t support standby. Standby is not supported on NT.
3.2.6 Hibernate
If your pc supports it, then this will put your pc into hibernate mode. If you get a strange error message, then probably one of your device drivers doesn’t support hibernate. You also have to have hibernation enabled in your power settings of the Windows control panel (Windows 2000 or above). Hibernate is not supported on Windows 95 or NT.
3.2.7 Lock
This action will lock your workstation. This is only supported on Windows 2000 or above.
3.2.8 Wake-On-LAN
This action allows you to start up a remote pc. This remote pc must support Wake-On-LAN. This means that you have to have a network card that is connected via an extra wire to the motherboard (or power supply) to provide some power. In the system BIOS, Wake-On-LAN must also be enabled.
How it works:
The network card constantly monitors the network for a ‘Magic Packet’ when the computer is switched off. This magic packet is a series of bytes that is sent over the network. A magic packet consists of a header (6*0xFF) and the MAC address of the network adapter repeated several times (16 times), for example if your MAC address is 01:02:03:04:05:06 (6 bytes), then the magic packet looks like this:
FFFFFFFFFFFF010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506010203040506
The nework adapter recognizes the sequence and triggers the power supply to turn on the computer.

3.2.7 Turn off monitor
This action will put monitor in standby (powersaving) mode. You need a monitor that is capable of this feature.
3.2.7 Turn on monitor
This action will turn on power to your monitor (get it out of stanby/powersaving mode). You need a monitor that is capable of this feature.
3.2.7 No action
Performs no action on the pc. Useful for only giving a warning message or running a program.
3.3 Where to do the action
3.3.1 Local Computer
When this radio button is selected, then the action is performed on the local computer. This radio button is unavailable when the action is Wake-On-LAN. This is because there’s no way that you can turn on your own computer...
3.3.2 Remote Computer
When this radio button is selected, then the action is performed on a remote computer. You have to click the ‘Specify’ button to specify on which remote computer to perform the action.
When the action is anything else than Wake-On-LAN, you are presented with the following dialog box:
Figure 2
- Computer name: This is the name (or ip address) of the remote computer
- Use NT protocol: When you select this, then the standard NT protocol/authentication is used to reboot or shutdown the remote computer. These are the only two options supported in this mode!
Figure 3
You have to specify whether you want to use the credentials of the user that you used to log into Windows. In that case, you don’t have to supply a username and password.
If your current account is not allowed to shutdown the remote machine, then you can specify another username and password to connect to the remote machine that has the rights to shutdown the machine. This username can be a username of your current domain, then you only need to specify the username and password. If the user is from a different domain or the remote computer’s local domain, then you have to prefix the username with the domain name (e.g.: DOMAIN\Username), see figure 3.
Note that if you currently have a drive mapping or printer mapping to the remote machine, you cannot specify another username, this is an NT restriction.
This mode is only supported from and to NT/2000 computers. No Windows 9x/Me support!
When you do not select the 'use nt protocol' checkbox, then poweroff must be running on the remote machine, either as a service or interactive with the ‘Allow remote’ option enabled.
When that is the case, then all actions are possible on the remote machine and it doesn’t matter which version of Windows is running there. Of course, you can still only perform actions that the remote OS supports…
- Password: Here you can specify the password that gives you access to the remote machine, leave blank if no password was specified by the remote poweroff program.
- Port number: Here you can specify the port number where the remote poweroff program is listening to
- Save password: When you save your settings in the main poweroff screen, then the password for the remote machine is also saved. This will store the password as plain text in the registry!
- Schedule on remote machine: When you don’t use NT authentication, then you can choose to do scheduling locally or on the remote machine. If you choose remote scheduling, then poweroff must be running on the remote machine and you can stop your local poweroff when the action has been submitted to the remote machine. Otherwise, you have to leave your local poweroff program running until the time arrives.
When the action is ‘Wake-On-LAN’, then you are presented with the following dialog box:
Figure 4
You have to specify the remote computer’s IP address, subnet mask and MAC address. The IP address and subnet mask are necessary to calculate the broadcast address. The magic packet is only broadcast to the right subnet. The MAC address is the physical hardware address of the computer’s network adapter. You can click the ‘Lookup’ button to find the hardware address. This performs a ping to the remote computer and then looks into the arp table for the IP address. This means that the lookup may not always work correctly. If the lookup fails, then you must get the MAC address from the remote computer itself by inspecting the network adapter’s properties. The MAC address is a series of 12 hexadecimal
numbers. Some adapters may display the MAC address as XX-XX-XX-XX-XX-XX, but in poweroff it must be specified without the dashes. This feature will only work on a LAN, not on a WAN or the internet.
3.4 When to do the action
3.4.1 Immediate
Executes the desired action immediately when you press the ‘Do it’ button.
3.4.2 Scheduled
Executes the action at a certain moment in time. Click the ‘Schedule’ button to specify when to execute the action.
Figure 5
In the time field, you can specify the time when the action must be performed. The time format is hh:mm (0-23 hours).
The date radio box lets you choose the days on which the action must be performed:
The date radio box lets you choose the days on which the action must be performed:
- Fixed day: Performs the action only once on the specified date. The date format is dd/mm/yyyy
- Daily: Performs the action on the days of the week that you specify. You can also select the weeks of the month on which to perform the action. For example you may choose to reboot your pc at each Friday of weeks 1 and 3. This option requires that you install the poweroff service.
- Day of month: Performs the action on a specific day of the month each month. For example you may choose to reboot your pc every 1st of the month. This option requires that you install the poweroff service.
- After x seconds: Performs the action after the specified number of seconds.
3.4.3 After a process stops
Executes the action when some running process finishes. Click the ‘Process’ button to specify the process.
Figure 6
Here you can type the exact process name or choose the name from the current process list by clicking the ‘…’ button.
Figure 7
Poweroff will poll the running processes every second. When the specified process is not running, the action will be executed. This can be useful for shutting down your pc when a certain program has finished or even as a watchdog to reboot the pc when a program that should be running has died.

3.5 Options
3.5.1 Warning Message
With this option you can give a warning message to the user before performing the
action. Click the ‘Message’ button to specify the message properties:
action. Click the ‘Message’ button to specify the message properties:
Figure 8
You can enter the number of seconds that the warning message must be shown. When the seconds have passed, then the action is performed.
You can also specify the message text that must be shown.
If you want a sound to be played when the dialog box is shown, then you can select the ‘Play a sound’ checkbox. Then you must also specify the sound file that must be played. If the action must be performed on a remote computer, then the sound file must also exist on the remote computer!
You can also specify the message text that must be shown.
If you want a sound to be played when the dialog box is shown, then you can select the ‘Play a sound’ checkbox. Then you must also specify the sound file that must be played. If the action must be performed on a remote computer, then the sound file must also exist on the remote computer!
3.5.2 Run a program
This option allows you to run a program before the action is executed. This can be useful to properly shutdown some other program before shutting down your pc. Click the ‘Program’ button to enter the program options:
Figure 9
You must enter the program that must be executed, or choose it from a list by clicking the ‘…’ button. You can also specify the startup directory for the program of select it from a list by clicking the ‘…’ button.
If you need to run multiple programs, then you should put them inside a batch file and then call the batch file from within poweroff.
If you need to run multiple programs, then you should put them inside a batch file and then call the batch file from within poweroff.
3.5.3 Force applications to close
This option is useful for forcing running applications to close. Otherwise some applications may not exit when Windows is shut down because they popup a dialog box or because they ’hang’. This option kills all running programs before logging off, rebooting, shutdown or poweroff.
This also implies that any changes made in running programs will not be saved, so for example if you have a text editor open with unsaved changes, then the editor will be closed without asking you to save the changes!

3.5.4 Visible in tray
When this option is selected, then the poweroff icon will be visible in the system tray when the ‘Do it’ button has been pressed and a non-immediate action has been selected. Otherwise, poweroff will seem to have disappeared and there’s no way to make it reappear.
3.5.5 Allow cancel
When this option is selected, then you will be able to cancel any chosen action (except when ‘Immediate’ execution is selected). You will be able to cancel the action from the system tray and in the warning dialog (if those options are set).
3.5.6 Allow remote control
When this option is selected, then other computers can connect to your pc and remotely perform all actions that poweroff supports on your pc remotely. This is useful when running poweroff as a service and when you’re the network administrator, then you can reboot remote machines from your pc. Click the ‘Settings’ button to specify remote control options:
Figure 10
You can specify the TCP port number where poweroff listens for connections. You can also specify a password that remote computers must enter before they gain access to your pc. This password is encrypted and stored in the registry.
3.6 Menu
3.6.1 File menu
Figure 11
- Save Settings: This saves the current settings to the registry. The next time you start poweroff, it will read these settings from the registry so that you don’t have to set your preferred settings again.
- Load Settings: This reads the settings from the registry and overwrites any changes made.
- Remove Settings: This removes all settings from the registry and restores the default settings.
3.6.2 Service
Figure 12
- Create service: This creates the poweroff service. This makes poweroff run in the background and can even run when you’re not logged on. The current settings are saved to the registry so that the service can run with these settings. When the ‘visible in tray’ option is selected, then the poweroff service is accessible via the system tray. The service will only execute some action when the ‘Scheduled’ option is selected, otherwise poweroff will just start up and will be visible in the system tray (if that option was selected of course).
- Remove service: This removes the poweroff service. If the service is currently running, it is stopped (only on NT/2000/XP). On 95/98/Me you will have to reboot in order to stop the service. Removing the service will also remove the service settings.
- Save settings to service: This will save the current settings to the service. On NT/2000/XP, the service will also be restarted to pick up the new settings. On 95/98/Me, you will have to reboot for the service to pick up the changes.
- Load settings from service: This will read the service settings from the registry and make them the current settings.
3.7 Event Logging
If you have Windows NT/2000/XP, then you can always check the event log (application log) for messages from poweroff. Here you can find information and error messages about the actions that were performed.
4 Command-line options
You can control every option and setting from the command-line. This makes poweroff excellent for use in batch files. Some options have changed since previous releases, so check your batch files! If you do poweroff /?, you will get an overview of all the options (look above for a description of all the settings):

5 Remote Control
You can remotely control poweroff by starting it as a service and setting the ‘Allow remote control’ option. You can control it by using poweroff itself and selecting a remote computer, or you can control it by using telnet to the port where poweroff listens on (default 3210). For example telnet computer 3210. You’ll see a welcome message like this:
201 Welcome to Poweroff 3.0 created by Jorgen Bosman
Poweroff uses a protocol like ftp or smtp with commands and reply codes. You enter a command and poweroff will reply with ‘2xx message’ on success or ‘5xx message’ on error.
You can enter the following commands:

When poweroff is minimized or it has a scheduled action, it sits in the system tray. You can right click the icon, then a popup menu appears:
Figure 13
- Restore: Restores the main window and removes poweroff from the system tray. Only available when not executing a scheduled action.
- Logoff/Reboot/Shutdown/Poweroff/Standby/Hibernate/Lock/Monitor off: Quickly performs the action requested. If the allow cancel option is disabled, then the action is performed immediately.
- Cancel pending action: Cancels a scheduled action and restores the main window again. Only available when a scheduled action is executing and the ‘Allow cancel’ option is activated.
- Exit: Quits poweroff

- Starting poweroff minimized no longer takes away focus of the running application
- Choosing a quick action from the tray no longer asks for confirmation when the 'allow cancel' option was selected.
V3.0.0.17: 31-03-2003
- Fixed bug: choosing WOL after the 'use nt' options was selected would return error.
- Added more logging with -debug option.
V3.0.0.16: 31-02-2003
- The -save_svc_set commandline option now automatically restarts the service if it is running.
- Added the STOP command in a telnet session.
V3.0.0.15: 05-08-2002
- Implemented workaround for Windows bug: Logoff while nobody was logged on caused Windows XP to display an empty screen and you were forced to turn off power. Poweroff now checks if a user is logged on before trying to logoff the user.
V3.0.0.14: 27-07-2002
- Fixed crash with new hibernate support
- Added -debug command line option to easily turn on debugging
- When the new hibernate/standby method fails, poweroff now tries the old method again.

- Added hibernate support for Win98/Me systems.
V3.0.0.12: 11-07-2002
- Moved buttons a little bit
- Enabled the poweroff action in Windows 95/98/Me. Some people reported that the system didn't poweroff with the normal shutdown action. Maybe this action does the trick.

- Fixed 'Invalid time specified' bug when doing remote action with scheduled 'after x seconds' time.
V3.0.0.10: 08-04-2002
- Fixed memory leak and improved performance a little bit when polling for running processes under win9x

- Fixed keyboard navigation. You can now move around the main dialog again with the keyboard.
V3.0.0.8: 23-02-2002
- Removed the use of gethostbyaddr() because it seems that this call queries the DNS server. This causes a problem when you do not have a DNS server configured.
V3.0.0.7: 16-02-2002
- Fixed a bug when \n\n was specified inside the warning message on the command-line
- If you just specified -remote m , then the default port number was 0. Now it's 3210.
- Added the possibility to generate lots of debug information. You can turn on debugging by creating a registry value HKEY_CURRENT_USER\Software\JoBo\Poweroff\debug of type DWORD and by giving it a value of 1. If you use the poweroff service, you can enable debug for the service by creating a registry value HKEY_LOCAL_MACHINE\System\CurrentControlSet\Poweroff\Parameters\debug of type DWORD and by giving it a value of 1. Then restart the service. Poweroff should now create a file called poweroff.log in its startup directory.
V3.0.0.6: 02-02-2002
- Added the possibility to enter a multiline message via the command-line by using \n as newline character

V3.0.0.1: 09-11-2001
- Now uses different socket library so that it can be used with Win95
- Fixed bug: Ordering of controls was wrong. This caused radio groups to be misaligned and caused the ‘visible in tray’ checkbox to be incorrectly turned off in win95/98/Me

8 FAQ
8.1 When I try to control a remote pc I get the message Connect(): Connection Refused(10061)
Make sure that you have installed the poweroff service on the remote pc after enabling the 'allow remote' option. Also make sure that there's no firewall blocking the poweroff tcp port (default 3210). You can test it by doing a telnet to the remote pc on the poweroff port, you should get a welcome message.
