My modest contribution: I created some videos showing how to install PostgreSQL and XWiki on Windows.
Installing PostgreSQL on Windows using SSPI: https://www.youtube.com/watch?v=GWb7t8J73Fc
SSPI is useful because you can authenticate to the PostgreSQL database using the Windows account credentials - all you need is a Windows domain account with the same name as the PostgreSQL database account.
Installing XWiki on Windows: https://www.youtube.com/watch?v=c2xUsnuDsBE
This video presumes PostgreSQL installation (from first video) and shows how to create the database, what files to download, and how to install to get a running XWiki instance on Windows.
How to request https certificate from AD certificate server for Tomcat: https://www.youtube.com/watch?v=2IfZApQtwDM
This video shows a demo of how to request an https certificate from an Active Directory certificate server (uses KeyStore Explorer GUI tool to make things easier).
Hope this is useful/helpful.
