what is the difference between
power user and restricted user
There isn't really an account as restricted user. You can place additional
restrictions on members of the "Users" group, but those restrictions would
vary because you enable them yourself.
Microsoft does not generally recommend using Power User, unless you have
legacy software that you cannot get to run as a regular user even after
changing file and registry permissions.
Another reason to run Power Users would be if you want to reduce computer
support overhead by allowing users to install some of their own software and
do other computer management actions without calling for help. Doing this
allows users to change their computer configuration away from whatever
default you've set up, and some environments find that undesirable for
support reasons.
