Keyboard Windows 10 layout problem

The best thing is if I give you my client's description verbatim. He has a Win 8.1  PC updated to Win10. He is connected to a Windows server SBS2008.

It looks like I’ve got an issue with how windows detects my keyboard layout. This is only a problem for my domain account. I’ve checked my local account and it works fine. The problem is, even my keyboard layout is set to UK, when I type it uses US layout. There are two keyboard layouts added as my preference (UK & US) in Control Panel -> Language (where UK has first priority). I tried to remove US layout but it keeps coming back when I reopen control panel.

This wasn’t a problem before. But if you remember my domain account had to be deleted because I couldn’t access internet and it was concluded that it’s due to a corrupt user account. Maybe it’s something to do with my domain account? As my local account doesn’t have any problem with keyboard layouts.

We tried various keyboard shortcuts trying to change the layout from one to the other and even tried to make the language bar appear in the task bar. But it none of them worked.
