I'm working on a computer where the @ and " keys have been reversed but in Regional Settings, all the 3 places where you can show a location etc have been set to "English (United Kingdom}". After applying those settings the computer has been restarted but the problem still occurs.
Is there any other way of getting the display on the screen to match the key that has been prseed?
Control panel / Regional and language options / Languages tab, Details button. On the new window, look at the Input tab and make sure the Default input Language and the Keyboard language are both set at English UK.
