How to install the shutdown software in win 8?
There always a few days each month my PC will shutdown at 8 am. Who knows how to set up for I don't want it shutdown? Thank you!

Is your computer running in your office or your private computer? If it is Pc in the company, maybe someone have started the firewall to shield something. As for the installation of the the shutdown software of Win 8, i have no recommendations for you, for I have not used it.
