I agree with the "sluggish" comment about Win 10. The issue I have with it, is it wants to update all the time and you can't start to work until it finishes, even though it should update on shutdown. I can't imagine the man-years of wasted time for companies using Win 10 waiting for the stinking thing to finish updating. On initial install, the setup routine reboots the computer a number of times, so there should be one of the "geniuses" at Microsoft who could figure out how to complete the update on shutdown and THEN shut the machine off and avoid the wasted time on startup.
