Nice tut Ray.

The problem with all this - is that it is a bit challenging for the average Joe.

Many people don't even know disk management exists, or powershell ( my dad for example - he has been using a pc several hours a day for over 20 years ). They would be apprehensive about doing anything in Bios setup.

These are the kind of things that act as barriers.

People will just put up with what they been have given - too difficult and (they think ), too risky to do anything about it.
