Up until recently, after every reset, I’d get a new language added to my language bar. And it was a strange one, Upper Sorbian.
It would always appear in my bar, but never in the language settings pane
I had a workaround that would remove the language until the next restart. It required manually adding the language and then removing it again.
Then, one day I finally clicked the
Change date, time, or number formats link on the left.
Apparently, my “Non unicode” settings under the
Administrative tab were for Upper Sorbian. Why? No one knows.
I changed my locale there and I made sure I clicked the
Copy Settings button and copied my User Settings to my other screens (
Welcome screen and
New User Accounts).
