Updated Answer based on your comments, First you need to create a button(preferably an Appbar button) and then place this code in the click event handler

NavigationService.Navigate(new Uri("/Home.xaml?home=true", UriKind.Relative));

And then in the Home page in the onNavigatedTo event handler place this code

string home;
NavigationContext.QueryString.TryGetValue("home", out home);
if(home != null)
{
    if (home.Equals("true"))
        while(NavigationService.CanGoBack)
           NavigationService.RemoveBackEntry();
}

So this clears all your back stack

Note: This is not any preferable or recommended way, its just a workaround!!

Add a button in every page (since you want to go home from every page) put the onClick to do:

NavigationService.Navigate("YoursView/HomePage.xaml", UriKind.RelativeOrAbsolute);

You may want to review the following MSDN documentation regarding Application Structure and Navigation Models :-

This worked.

1. Globally I declared a Boolean variable set to false in a class.

2. Then whenever the home button is clicked bool variable is set as true and navigated back.

   Modules.HomeClick = true;
   NavigationService.GoBack();
   

3. Then in every page for page loaded event I checked condition if bool variable true go back.

   if (Modules.HomeClick=true)
   this.NavigationService.GoBack();
   

these done in every page till homepage.This do not store backstack.
