First of all, the current windows version of the OCS server is not up to date...
In order to obtain a recent version of the OCS server, it is advisable to choose the Linux version or wait for a future version of Windows (several important updates are not today included in this architecture).
For testing purposes, you can always try the Windows installation but let it be really different from the one in Linux (you can also use a virtual machine like CentOs or Debian, for example)
> If you are in a production environment and your server will be accessible from the Internet, I recommend Linux.
Otherwise, for the installation of the server under Windows, the tutorials are actually more rare or obsolete ... Finally, the best would probably be to buy a book on the subject ... Do you speak French ?
