Personally I'd say that we need to know what Windows thinks it's set to.
If you have seen the prior post, I've made it simpler.
Hold down the Ctrl and Shift keys (the two bottom left are easiest) the whilst holding them down press the Esc key.
Task manager will run. Click on the file menu (top left) and select Run new task.
In the dialog to the right of the Open: type powershell_ise
Just below check the check box which says Create this task with administrative privileges
Click on OK.
When the blue box box opens, type the following
Get-Culture; Get-WinSystemLocale; Get-WinHomeLocation; Get-WinUserLanguageList
and press enter.
It is case sensitive but you can also copy and paste it from this window if needed...
You will get a lot of white text. Click on the Edit menu above. Near the bottom click on Select all. Press Ctrl and C keys together.
Now you have the text copied you can simply press Ctrl-V in a VV posting box or right click and select past from the little menu.
With this information we'll know exactly what Windows is set to.
Mine looks like this. Yours will be different.
