Windows 10 is so frustrating

I regularly help out older folk with their computers. Some of their difficulties are down to how they are doing things wrongly or to arthritic fingers and they can be forgiven for that. Time and again, however, the problems they have result from wretched Windows 10.  Technology (and any product in fact) is subject to a process called "continuous improvement" which is why there are so many updates and newer versions of everything to be temptingly downloaded. Worse still, the default with Windows is to install updates and features automatically unless the user carefully monitors update processes.  Even when an update is accepted, it often happens that the display settings and desktop layout (the User Interface [UI]) change significantly from before the update.  Nothing is guaranteed to confuse an older person more than to change something they have managed to get used to.  The trouble with software today - and Windows is typical - is that it is so packed full with features that the average user would never need. I always say that it is like being compelled to buy a Rolls Royce when all you need is a Mini to get to the shops. Why can't big vendors produce cut-down, simple versions for those who don't want and will never use the "bells and whistles"?
