Is it possible to determine (programmatically) if system was just powered up or rebooted

From: Boris on 10 Jul 2010 18:40 Hi, I'm thinking about writing custom Native EXE that will be executed early during Windows boot process. I'll put pathname of my Native EXE into BootExecute value in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager key. But I need to tell "cold" boot from "warm" boot: if hardware was powered on or just Windows restarted. Is there a way of doing this? Thanks, Boris

I was going to say just check the value of GetTickCount(), but that's no good if the user has rebooted the PC. Maybe check that once, and store a flag value somewhere (with the date) so that subsequent checks on the same day know that the PC has already been previously started that day? That should work fine.

It's possible, some HAL lib functions can extract that info from system BIOS - but I couldn't find anything relevant. Boris

You can find out in a driver from the power state transitions what the user intended to do at shutdown, but this does not ensure that you will get the result. For instance, the person who chooses reboot then pulls the power. If you can live with that restriction, there are approaches, otherwise the comments so far are probably about all you can do.
