Why does Windows insist on updating itself--yet why do I see no noticeable "update" and everything is just as slow and just as erratic? Exactly what is being updated? Whose benefit is the update for if it isn't mine? Why is it that, despite my Clicking on "Make no changes to my computer", changes happen anyway? Why am I told "Restoring your previous version of Windows" when it is actually being updated no matter what? Are there no reliable, 21st-century alternatives to Windows?
