Insider Preview Update Error and Unenrollment

For the past 3 days, I have have been informed that i have an Insider Preview Update to install. Each time it says, can't complete installation due to some files missing. Not to worry the message says, as it will try again at another time to download what I assume is those missing files. This is the 4th day, and same issues. I contacted Live chat support, and that agent couldn't help resolve the issues, and send me over here. I had to do a clean re-install, because an insider preview update screwed up my graphic so bad, I could not see anything on the screen, much less to log on. After the clean re-install, the system boot me back into the Insider Program, and so I tried un-enrolling, to no avail. I enrolled in this preview build version because I wanted to assist Microsoft with whatever it is that they were trying to improve with the user experience, but I regret it. I am trapped, with no way out of this problem. Anyone out there that can assist me escape this madness?

    Hi Deuce1,

    I can understand your frustration, especially after having to perform a clean installation because of a previous Insider build.

    A couple of questions that may help narrow this down:

    • Which Insider channel are you currently enrolled in (Canary, Dev, Beta, or Release Preview)?
    • What build number are you currently running?
    • When you try to leave the Insider Program, do you receive an error message, or does Windows simply keep offering Insider updates?

    If Windows automatically re-enrolled you after the clean installation, I wonder whether the device is still linked to an Insider configuration through the same Microsoft account.

    As for the update failure itself, do you happen to see an error code in Windows Update history? That could provide more clues about whether this is a download issue, corrupted update files, or something specific to the current Insider build.

    Let us know what channel and build you're on, and someone may be able to provide more targeted suggestions.
