I need an shutdown timer application that can run on Windows XP. I would like for it to require a password to cancel the timer.
Use the built-in shutdown timer in windows,
To initiate a shutdown, use the following command from the command prompt. You can also create a desktop shortcut to it:
To cancel the command, open a command prompt from an administrator account, and type
This will stop any timed shutdown in progress. To create a shortcut that will let any user do this if they have the administrator account's password, use:
This will open a command prompt asking for the administrator account's password, and will then stop the shutdown.
If you need more control than these options offer, you may need to look for a third party program. These options however will work for any Windows computer and are built-in. You can also run the timed shutdown from a scheduled task if you want the shutdown to occur at a certain time every day.
As this question did not have a good answer (unless you are going to do some coding) I am inclined to say neither does yours.
In addition, what is to stop someone from just killing the process? Nothing a process can really do to prevent it.
