Keyboard issues....
Ah yes, sorry about that. I normally use a wireless keyboard with MS 'intellitype' software installed, so I get different software to adjust. (Have removed it for this problem).
There are three things you can try. If you have two different keyboard layouts enabled, you can switch between them by pressing 'Ctrl' and 'Shift' together. Repeating that will go back to the first one.
If it's not that, do you have a small keyboard icon showing in the taskbar (lower right of screen)? Or maybe two letters such as 'EN' or 'US'? Move cursor onto it, and right-click, select 'settings'.
In the 'General' tab, you will see the languages of the keyboard layouts you have installed. In the box you will see the options, the top one is the 'default' for your computer, in my case 'EN English (United Kingdom), then dropping down below are some options, depending on if you are using a laptop or full keyboard (extended).
Click once to highlight the wanted one, then click 'OK'.
In my case it's 'United Kingdom extended'
Now your keyboard should be standard layout.
*(If you don't have the keyboard icon showing in Taskbar, move cursor down onto the Taskbar, right-click.
Move cursor up to 'Toolbars', a box will fly out to left, move cursor across to 'Language bar' and click on it once. Now you will have ticked it, and a keyboard icon will be in the taskbar).
Hope that helps,~and works.
