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.
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.
