Hi, Are you using the final version? Have Dual Boot with Win7? It may be that if dual boot is used with Win7 Win8 will not turn off, technically Win8 never goes out, but we recommend you order off the machine and this close everything and Physically off, the OS makes the kernel into a state of drowsiness technically the OS is never although he cut the power off or at least the kernel, if it closes properly, reason when pin is quickly started, Tuquito MS, I I mention to be understand why it is as it is.
You have the following test to see if it causes the system to shut down, but this will make Windows really goes and if I start it slower.
run the Notepad and paste the following.
shutdown / s / t 1
Then you save the document, and give the name of Apagate.bat, do you save it in the Documents folder, the My Documents travels, searching the file and paste it on the Desktop.
Doubleclick on that file, it is not technically necessary to program that ran in administrator mode, you do not, is indistinct, the Apagate.bat run by opening a CMD screen and the system will start the closing process and should go.
Try to see how it turns out, for now is the method I know of to force his off, if this defies the law generally is a command that is to been using to shorten the officer walked, and make shutdown more direct SO.
