It doesn't help when even experienced users suddenly find something in the OS or application has been updated. What you used to be able to do in your mind's eye - is no longer accessible in that way.
A colleague used to keep a logbook of every change he made to install or tune something on his PC or the network devices. The problem was that over 40 years the data became very voluminous. It had no index - so eventually he often couldn't find the information. When he retired the last thing he ever wanted to do was to be an "expert" in such things again.
It becomes a never-ending task of keeping plates spinning.
When you want to use your PC to do a job - you don't want to have to trouble-shoot why some essential function no longer works.
