Trying Ctrl, Alt and Del does not work most of the time. I have had my PC hang with no way to use short cuts. Forcing you to force the PC to shut down.
Having updated Windows 8 I have found it to be the worst OS to date. All of the event logs are the same, yet the PC hangs where you can do nothing but do a hard reboot. Go to the event viewer and shows the hang log, but can not find any problems when you try to go and search for it on Microsofts...
