2017-01-11T01:43:36+00:00 Windows 10 does not run that way. There is no "left pane" to select "run as administrator. As all of these "answers" do not give the correct steps for Windows 10!

2016-09-14T20:09:24+00:00 This would be fine if it wasn't Windows Module Installer that was eating up my resources. It is at the top of the CPU usage list, using close to and over 40% of the cpu resources. task Manager is also using close to and over 40%. So between the two, my computer is basically not usable. And I spent over an hour yesterday installing the most recent updates. Now it is WORSE than it was.
