Client VPN Windows don't recognize PPTP settings

Hello,

All tutorials i’ve seen on the internet, when user need to setup windows client, just need set IP, User and Password, and all settings (VPN Type, criptography…) recognize automatically.
But on my VPN (PPTP), i need to set all configurations manually in Windows Clients, Android client works fine…
What may be this problem?

Sorry for my english, i’m Brazillian and i don’t speak english very well…

Thanks for Everyone…
