Oh, just found the answer in another thread.

I've downloaed an app from the store and this made my local account to be authenticated against my Microsoft-account.
How can I revert back the account to be a local account?

Thanks in advance...

No, I mean font-smoothing. I've disabled ClearType for the system and got better results for all other applications except Internet Explorer and Edge.
With font-smoothing I get ugly looking fonts...

Does anyone know how to disable font-smoothing in MS Edge?
The system-wide setting doesnt work.
