Integrating cumulative updates into install sources

During the Insider Preview phase, several tens of thousands of different configurations will be tested, but there will still remain some minor hiccups in the very first ISO/WIM released directly at GA (typically this version is something like 10.0.14393.0). If you have a .0 image or with a low one digit number at the end, you should integrate yourself into the latest cumulative update. Do not wait four months until the declaration of CBB and auto-update of sources.

Upgrading your install.wim is very easy. Download the latest cumulative update from Windows Update Catalog. Unpack the ISO and mount the included install.wim to a temporary folder. Add the .MSU file with DISM.exe, commit the changes, and unmount the WIM file. To reduce unnecessary growth of the WIM file, start over each time with the original WIM.
