Accounts :: Local Account Converted To Microsoft - Any Way To Reverse?

My local admin account was converted into a Microsoft account , is there a way of reverse it ? Less than one month ago Windows 10 Pro was installed. Let me explain you that there was already a windows 8 installation with kernel corrupted , version 10 recovered all exactly as it was , all programs installed and my configurations.

Previously I had a administrator local account that remained the same after windows 10 installation. It happens that days after I logged in with my Hotmail account to the Microsoft Store to download a couple of items and unbeknownst to me my local admin account was transformed into a Microsoft account.

Now I no longer wish to be logged all the time with this Microsoft account, I even have another admin local account if I want to change but I would have a lot of work to make it look like as it was my original converted account.

In order to avoid such work I ask whether there is a way to convert (let's call this way) the Microsoft account back into my local account or is there a way of copying all the configurations to a new admin local account ?
