I have Windows 10 & I am the only user. It's a Surface Pro 3 if that helps.
One day out of the blue, my language bar disappeared. I've tried pretty much everything short of formatting my PC.
I've done the whole, turning on the input indicator/adding and removing languages I've tried restarting explorer.exe
I am trying to use English and Simplified Chinese.
As a test, I added in German and it will change with Alt + Shift to German but it won't go to Chinese (or it does but still uses roman alpha) I know because in the German keyboard, Y and Z are switched so I can tell when I'm using one or the other.
Also my " tablet " keyboard will show the German or Chinese characters, but seemingly won't switch. Like it gets stuck, but my typing will still indicate when I'm in German vs the other two.
It's basically ALL out of whack, and I just don't know what to do anymore and it's a big problem as I live in China. I need to be able to type in Chinese.
