Windows Installation scripts modification : 
Modifications on install command lines for windows, Modification of template for windows hosts (check_windows_host_alive) only for the windows's shinken installation. New downloads location (check_wmi_p lus 1.56 already set for windows's shinken and check_nt compiled nagios plug-in)
Added, check_winping to be compliant with windows_host_alive to workaround the issue with check_tcp on windows.
