For those of us who use 3rd party start menus, upgrading to Windows 10 1607 can be a shock. The upgrade removes Classic Shell which would be fine if all users knew how to put it back.
My clients do not know. They ask me to give them something they recognise, and I do it for them because they are not interested in technicalities.
A question … What is it about Classic Shell that is so bad that it has to be removed? Removal just sets in panic and some users call bogus ‘help’ companies, turning a bad situation into something much worse…
