HOWTO fix Windows 10 installation blocked in updates searching phase

Several weeks ago, I updated an old notebook from Windows 8 to the latest Windows 10.

One of the problems, I faced is that the W10 installation hung in the updates searching phase.
From my investigations, it seemed a Windows Update problem of the almost phased out OS.

Simply I didn’t want to fix a problem in an OS that I was going to wipe out.

The Solution

After few failed tries, the solution was to disable this setup phase.

To do this, you cannot use the Media Download Tool to start the installation but you have to:

  • locate the downloaded W10 setup folder ESD, (usually: c:\esd).
  • open an administrative Command Prompt.
  • go to <esd>\windows folder (usually: c:\esd\windows).
  • start the installation by the following command line:
setup /auto upgrade /dynamicupdate disable

It will start the installation process, skipping the blocked phase, and allowing you to apply the latest updates when the new shiny W10 is up and running.
