Transfer Everything to a New User

Sep 3, 2018
I changed the username on my PC a while ago. In some instance, it will display the current user name in the windows explorer bar, other times it will display the old name.

From what I've gathered, this will occur unless I move to a new user profile entirely. Is there a way to transfer everything from my current profile to a new one quickly and keep everything (such as desktop icons and their layout, programs pinned to the task bar and start menu, etc) looking the same on the new profile?
