Cannot disconnect live account

[Schnippzle]

So I performed a clean install of Windows 10 Pro 64bit, created a local account, logged in, enabled local admin and have been using that quite happily since.

Then I tried the Xbox streaming app which has now changed the local admin account to a live account. Microsoft say that to disconnect this, I need to go to Start -> Settings -> Accounts, and within "My Account" there should be a link to disconnect the account. This link isn't there and it's now preventing me to run apps that need admin access unless I go back to right clicking and launching as admin. Is there any way to force a disconnect?

E.D.I.T.: There is also no option to "switch to local account".

The weird thing is: within computer management, the only enabled account is the account I'm supposedly using which is called something else (what I originally named it).

Seems adding my pc to a domain doesn't resolve the issue either. Seriously looking like a potential reformat
