For Windows users, see current value of the LANG environment variable with PowerShell like so:
```powershell # User context / per user [System.Environment]::GetEnvironmentVariable('LANG','User')
# System context / all users [System.Environment]::GetEnvironmentVariable('LANG','Machine') ```
If no value is returned, it hasn't been set.
<hr>
And set it like so (in user context / per user, does not require admin):
```powershell [System.Environment]::SetEnvironmentVariable('LANG','en','User') ```
