I followed the thread and got totally lost. Is Microsoft aware of the problem? It does not have to be that complicated. The language bar is an essential and simple thing that shouldn't require jumping around. It doesn't work for me, the option "docked to the task bar" is grayed out.
I used windows 7, 8, 10 - never had a problem with it
In the much louded windows 11 it's not working
Microsoft, wake up
