There is one function, however, that has been known to exist but is not documented anywhere (or at least not in any source I’ve seen). That function is NtSetSystemPowerState. It’s known that NtShutdownSystem calls NtSetSystemPowerState at the very last stages of the Windows shutdown process after flushing all Registry hives, clearing the disc cache, etc. NtSetSystemPowerState is then responsible for turning off all plug-and-pray devices and either telling the system to poweroff, reboot, sleep, or hibernate.

The formal definition of NtSetSystemPowerState is the following:
Code»

Note that on systems with NT4.0 or earlier, NtSetSystemPowerState does nothing, and only returns a STATUS_NOT_IMPLEMENTED message.

Both POWER_ACTION and SYSTEM_POWER_STATE are documented on msdn, while flags is simply the reason for shutdown, also documented on msdn.

For some, this is an absolute miracle. For others, this isn’t much. Either way, I’d like to present to you AMailSender – a program to send anonymous emails from any email address you want.

I believe the UI is pretty self-explanatory, so I’m going to leave you to figure out how to use it. The only problem some users seem to have is with the SMTP server. SMTP server means Local SMTP server, not any SMTP server you want. For the more technologically inclined, the server has to be open-relay, which means either it has to be the one your ISP uses, or some other open-relay one (which are very rare).

Also, I am aware that the program crashes when trying to attach certain files of type EXE or COM. Please bear with it, I’m going to fix it as soon as I find some spare time (which’ll probably be in March/April). I’m getting swamped with schoolwork right now.

Finally, thanks to Oakwhiz for pointing out that the “Find” button for SMTP servers does not work. I was calling DnsQuery wrong, and will fix ASAP. Until I attempt to fix it, here is a tutorial on how to find your SMTP server. If you are not using MS Outlook, I recommend using this to find your SMTP server.

If you find any other bugs, please comment. Your responses are highly appreciated. (Would someone please test this on Vista as well. Vista is allergic to many of my apps)
