Change Windows display language from .Net

Question

Is there any API available to change windows display language? I want to update system setting.

Answer 1

A way is to use Powershell Automation

Tested on Windows 10 21H1 (need reconnection) :

                // Add reference to : "C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell\3.0\System.Management.Automation.dll"

                // Should use Get-WinUserLanguageList to get the list
                string sLanguage = "en-US";
                using (var ps = PowerShell.Create())
                {
                    string sCommand = string.Format(@"Set-WinUILanguageOverride -Language {0}", sLanguage);
                    ps.AddScript(sCommand);
                    Collection<PSObject> results = ps.Invoke();
                }
