Yesterday I had an issue with a failed system restore which caused my machine to not reboot correctly. I think I may have been the cause of the issue, as when system restore was automatically shutting down Windows, I clicked a cancel button in one of the dialogs (I believe for Outlook mail), which asked if I wished to exit whilst email was still in my outbook waiting to be sent. This caused the shut down process of windows to simply hang.

Executing this process from Task manager (that I was able to open using Alt+Ctrl+Delete shortcut), brought up a dialog that allowed me to undo the system restore I had just done. This then solved my issue after the machine rebooted correctly…. PHEW!!! Big relief as I thought at one point I was going to have to reinstall Windows and all my applications again.
