Problem CreateProcessWithLogonW with Date Format Windows 10 v.1703

Question

I have the following code, where I raise a process using other Windows credentials provided in an external source.

Code:

 public static void ImpersonateProcess_WithProfile(string appPath, string domain,
        string user, string password)
    {
        ImpersonateProcess(appPath, domain, user, password, LogonFlags.LOGON_WITH_PROFILE);
    }

    private static void ImpersonateProcess(string appPath, string domain, string user,
        string password, LogonFlags lf)
    {
        StartupInfo si = new StartupInfo();
        si.cb = Marshal.SizeOf(typeof(StartupInfo));
        ProcessInfo pi = new ProcessInfo();

        if (CreateProcessWithLogonW(user, domain, password,
        lf,
        appPath, null,
        0, IntPtr.Zero, null,
        ref si, out pi))
        {
            CloseHandle(pi.hProcess);
            CloseHandle(pi.hThread);
        }
        else
        {
            throw new System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error());
        }
    }

This program works perfectly for me in the version of windows 7,8 and 10 ..

But in windows 10 version 1703 I am dealing with an error by date format (Said error thrown by validations of the running process) .. I do not understand why this happens only with this version.

The error comes because the running process expects the date format to be dd / MM / yyyy. But I repeat this only happens to me only in this version of Windows 10 and sharing the same date format in all the versions I've tried.

1703 is out of support (except the Surface Hub Edition) Does it also occur in 1909? — magicandre1981, Mar 04 '20 at 15:42
@magicandre1981 thanks for your response, and this only occurs in 1703 versions, in the 1909 works. Can you show the link that talks about the versions support? — Carlos Reyes, Mar 04 '20 at 16:43
This is explained [here](https://support.microsoft.com/en-us/help/4018124) **Windows 10, version 1703 has reached end of service for all editions. To continue receiving security and quality updates, Microsoft recommends updating to the latest version of Windows 10**. This page shows last update was [October 2019](https://support.microsoft.com/en-us/help/13853/windows-lifecycle-fact-sheet). 1709 will reach end of support for Enterprise edition in April 2020. So check if your app runs on the supported versiond and LTSB/LTSC versions. — magicandre1981, Mar 04 '20 at 20:48

Finally i found a solution that helped me.

I just create a bat file where i change the system date format and then i run my .exe

@echo off
reg add "HKCU\Control Panel\International" /f /v sShortDate /t REG_SZ /d "dd/MM/yyyy" >nul
app.exe

This works for me.
