Just an FYI, on 12/26/15, I downloaded the Media Creation Tool and created an ISO. I installed Windows 10 with the host machines internet connection disabled (to ensure updates weren't being downloaded and installed during setup) and the install is in fact the November Update, Build 10586. Just missing the .36 Cumulative Update.
See the screen shots below, during the install the "Date Modified" shows 10/30/15, which is when Microsoft compiled this release for the November roll out and the second screen shot is immediately after my first logon, showing build 10586.
