This update don't arrive to the end of the installation.

The PC download the update, install. reboot and at this point a dead windows is displayed.
The PC shout down, uninstall the update and restart as was before.

I try 3 times the upgrade but was not possible.

Same trouble, both attempting upgrade through Windows Update and by iso image.

Insider Builds are for testing and evaluation an such errors are expected.
In case you are able to boot into the Windows, open start and search for the Feedback Hub app and report this issue.

It is highly recommended that you report this problem via Feedback hub. Alternatively, you can try upgrading a newer build i.e. 21390 and check if issue is fixed on that.

@daniele1357 Same. I uninstalled my video card drivers and it worked the last time I had this issue. About to try that again
