Windows Remote Support, Me
I do the tedium and optimization of Windows operating systems for home users that is beyond their knoweldge. Not their fault, as I tell them "how do you eat an elephant?".
Just too many things to learn for the average user who wants the computer to power on, open a browser and do their email or launch Office to do word processing.
I also optimize IT Professionals computers whose focus is on their coding, not the operating systems performance.
