16188 won't install for me. I had a general windows tech try to troubleshoot.... 2nd guy wanted to re-image my device without even asking if I had backup.... any ideas why this build won't install?

I'm having the same issue.  Guess I'll wait for the next build.

John, whatever the last technician was trying to do, he really messed things up (disabling processes, deleting registry keys, deleting system files, etc...). I started getting errors even trying to connect to the update servers. So, I decided the run the windows update repair tool again (4th or 5th time), and it must have fixed everything. 16188 installed successfully afterwards.
Could you please submit feedback on this in the Feedback Hub App if you haven't already?

Well, for my laptop, 16188 is giving me green screens of death at two minutes after log-in. I even had trouble filing the feedback as the machine would crash. So, I guess I will have to wait for the next build and install it via a USB stick. 

Hi Pierre -

Could you please submit this note in the Feedback Hub App if you haven't already?  That way I can reference it to the engineering team.


I did submit it and even put my machine on monitoring for a few seconds, not more as it would crash. I will add more data to my request using the other machine.

I added some more data about my machine to the feedback hub report. Title starts with "16188: Repeated Green Screen of Death...". I also paused the updates to my other machine as I cannot afford having that one on GSODs.
