Since beginning of
Windows Insider program we geeks have had a possibility to convert the ESD file of new upgrade build to an ISO image (
tutorial). With it we could create DVD / USB install media to be used in clean, in-place and repair installs.
Since Windows 10 Insider Build 14986 Microsoft has started to use new
Unified Update Platform (UUP), which no longer offers the
install.esd file (read more in
this post). Through some registry modifications users can at least for now disable
UUP and get
ESD version of the build upgrade, but it seems that this option might not be available in the future.
UUP is of course a positive change. It is differential, scanning user's existing Windows 10 installation only downloading and installing those system files that have changed. In ESD upgrade full Windows system (all system files and native applications) were replaced, with the same file or app version even in case the new build did not include a newer updated version. Regardless if a system file, component or application was updated, ESD upgrade replaced it. This caused download size to be bigger, in addition to longer time required for upgrade because full Windows was downloaded and everything overwritten with every upgrade.
However, the possibility to create an ISO image is, has been and will be important to many users. Microsoft has usually released an ISO when a build has been released to
Insider Slow Ring, but we
Fast Ring users do need an option to create our own install media.
This tutorial will show how to do that, how to create an ISO image out of a UUP upgraded Windows 10.
