That doesn't change the answer a single bit. If it didn't work for you then you did something wrong.

It should change for everyone.Including Welcome screen and UI-language and Display language because I'm supporting MUI

Oh.... then install a different language specific version of Windows. You don't get a different language just by changing a registry setting.

ok just forget all above.Is there any possible way if i use any method it will change for all.

Yes there is. Install a version of windows for the language you want the user to understand.

Localization is more for things like datetime formatting, currency symbols, etc.

The OS itself determines what language to present to the user, based on user settings.

Philippe Mori 17-Oct-16 9:05am

Each user select their own language for the OS. And if your application is multilingual, you can allows each user to select their preferred language.

You should never change the language of existing users. And if you want Windows in a specific language, then it is better to install Windows only in that language. You can always specify default parameters for new users. Thus you should have the appropriate language set before creating the first user. And if you change language afterward, you always have the risk of some parts or third party applications to not be in the desired language as they might use the langage that was active when they were installed.

The OS determines the language to display. If you insist on overriding it (bad idea), do this when you init your app:

C#

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo(Properties.Settings.Default.language);
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo(Properties.Settings.Default.language);

The language is stored in the user specific part of the registry (file NTUSER.DAT in the user directory).

When the user is logged in, you can access the user settings at HKEY_USERS\<SID> using regedit or the Windows API registry functions called from a program with administrative privileges. When using a program, the users must be enumerated first to get their SIDs.

When the user is not logged in, the registry can be edited offline using the Reg[^] utility. See for example Modify the Registry of Another User[^].
While this is not a C# solution, it should be no problem to execute the commands or write them to a shell script that can then be xecuted.

What I have done is loading the UI-language from a text file. After the user has been loggedvin. It wil change to the user preffered language. All the text comes from resource files. for example:
Resources-Errors.en-US.resx
Resources-Errors.nl-NL.resx

C#

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(Properties.Settings.Default.DefaultLanguage);
