encfs4win mount at boot

[newer]

Hi,

I'm trying to create a bat script like this to be executed at boot or
user login at windos 7:

Encfs4win c:\cripted d:\

at the moment works perfectlly, a cmd windows opens and ask for
password. The problem is that cmd windows remains open executing
encfs4win, if i close it encfs4win stops working and drive is
unmounted.

What can i do to have the cmd windows being closed and encfs4win
runnig after user supplies password?

Thanks.
