The best thing that can be said about Windows 8 is -- "Upgrade to Windows 10 as soon as possible!"
Windows 10 is what Windows 8 should have been. Most of the annoyances from Win8 are gone. Microsoft would like to kill the Win8 Operating System ASAP.
Win8 seems to have recently started not allowing BarrelTime to kick into Administrative Mode. Could it have something to do with one of the nearly daily Win8 updates?
