My main development machine is an Alienware 15 R3, a very powerful and nicely colored machine and, as many of you I wanted to install the latest release of Windows 10, the April 2018 update a.k.a build 1803.
Unfortunately looks like it was not possible because of this issue

A quick search on the internet and a hint from my colleague Emanuele lead me to the solution.

1-Get the update iso (i got mine from MSDN…)
2-Go to device manager and un-install device drivers from all of your graphic cards
3-Enable Airplane mode

Launch the installation and enjoy the April 2018 update
