I experienced this issue after upgrading to the Windows 10 anniversary edition (build 1607) several months ago. After pouring over various forum posts, disabling 'fast startup' in the power options seems to have fixed the issue for me.

And by "Beta", do we mean "RTM"?

Alternative fuels have always been repressed by the US government and big auto makers because of the global dependence on oil. Do you think it has taken us 50 years to get a car to go supposedly 40mpg?

Back in the late 70's there was a little know company called AMECTRAN, that a the first production ready electronic vehicle that could go 80mph, had a range of 100+ miles, and costs less than $10,000. Electric cars suck? Yea right! Take a look at the inventor's website: http://www.amectran.com/ .
