theres a bios option called restart after power loss. enable it
This is a really bad Idea you will corrupt windows files and could damage Hardware so it amazes me this is the best answer well good luck when you have to reinstall windows every two weeks after turning your computer off this way. I swear that is the DUMBEST thing you can do to a computer but I guess if your rich and got money for harddrives failing and have time to reinstall windos and dont mind loseing information have fun but shovenose Idea is not a smart move at all that option is meant for emergenct power loss not for doing what you are asking.
Well have fun wrecking your computer.
