Change the OS region format all at once

Here is the scripts I have wrote to do this.
Hoping this can help someone someday :)

Basically I have tools to change only the decimal separator and some to change the settings to a predefined OS one.

In order to change the OS Region, i had to run using a powerscript command to have the effect i wanted. 

/**
 * Sets the decimal symbol for the user's locale settings.
 *
 *  {string} separator - The character to be used as the decimal separator. Default is '.'.
 */
function Locale_SetDecimalSymbol(separator = ".") {
    // Sets the system's decimal separator to the specified character.
    // LOCALE_SDECIMAL: Constant representing the setting for the decimal separator.
    SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SDECIMAL, separator);
}

/**
 * Sets the thousands separator for the user's locale settings.
 *
 *  {string} separator - The character to be used as the thousands separator. Default is ','.
 */
function Locale_SetThousandSeparator(separator = ",") {
    // Sets the system's thousand separator to the specified character.
    // LOCALE_STHOUSAND: Constant representing the setting for the thousand separator.
    SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_STHOUSAND, separator);
}

/**
 * Sets the list separator for the user's locale settings.
 *
 *  {string} separator - The character to be used as the list separator. Default is ','.
 */
function Locale_SetListSeparator(separator = ",") {
    // Sets the system's list separator to the specified character.
    // LOCALE_SLIST: Constant representing the setting for the list separator.
    SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SLIST, separator);
}

/**
 * Sets the locale settings to a given culture.
 * Culture must be in a format such as 'fr-FR', 'en-US', etc.
 *
 *  {string} cultureString - The culture to set the locale settings to.
 */
function Locale_SetSettings(cultureString) {
    WshShell.Run("powershell -command Set-Culture " + cultureString, 1, true);
    Log.Message("Setting culture to " + cultureString);
}

/**
 * Sets the locale settings to the French culture (fr-FR).
 */
function Locale_SetFrenchSettings() {
    Locale_SetSettings("fr-FR");
}

/**
 * Sets the locale settings to the English US culture (en-US).
 */
function Locale_SetEnglishUSSettings() {
    Locale_SetSettings("en-US");
}
