ShutdownGuard tries to prevents applications to shutdown, reboot or log off your computer. When it prevents a shutdown in Windows XP, it will pop up in the tray and ask you if you want to continue. In Vista and Windows 7, you will see another dialog.

Note that ShutdownGuard will not be able to prevent all shutdowns, since some programs explicitly tells Windows to force the shutdown. This means some programs will still be able to shutdown your computer!

Sorry for the recent "outage". The project was locked for review since Google suspected it for distributing malware. It has now been cleared and I hope they don't redo the mistake. Read my thoughts about the incident here.

I have made a video explaining how to compile SuperF4, which is another program of mine. The instructions also work just as well with ShutdownGuard. This might be of interest if you are learning programming and want to make your own modifications to ShutdownGuard. Go to the Build wiki page to see it.

Released 1.0. In this version I have removed PatchApps. It has now been separated to a new program. The release also fixes a couple of minor bugs and is also available in 64-bit. The installer will automatically install the correct executable. I decided to bump the version number to 1.0 since I consider ShutdownGuard feature complete.
