My user profile directory on my PC is `c:\users\efrea`, which is exceedingly annoying given my muscle memory typing out my username. I "fixed" this with a couple junction points (both `efreak` as used on my Linux systems, and my first name as was used on my previous Windows systems), because I frequently use RDP from my android tablet and autocorrect keeps changing it to my full username. This is the second annoyance after finding out early on that changing my username doesn't mean changing my profile directory name (at this point there's too much software and scripts with hard-coded paths, both locally and remote, to change it without leaving the junction).
I would vastly prefer my username to be my usual username, with the display name being my real full name, but my Microsoft account apparently doesn't allow this (likely due to my privacy settings).
