    Windows 10 2004 update unsolved and now error 21H1 0xC1900101


    Now that I tried to install update 2004 and now 21H1 and it has proven impossible to do so. As always I get error 0xC1900101. I have tried so many reboots that I am surprised the hard drive is not crashed. Clean boots, disable drivers, change system settings to hide all Microsoft services, and disable non-Microsoft ones all fail with the same error.I have tried all the things Microsoft tells you to do on their pages and I keep getting the same error. The only thing I have yet to try is a clean install of Windows 10!

    :)

    Error 0xc1900101 0x40017 when updating to 2004

    Hi, I am trying to update my windows 10 pro from 1909 to 2004. I tried already 3 times, the first twos with windows update and the latest with the iso. However they end with the same result with the error 0xc1900101 - 0x40017 "the installation failed in
    the second_boot phase with an error during boot operation".

    I found this page https://docs.microsoft.com/en-us/windows/deployment/upgrade/resolution-procedures but I don't have Citrix VDA
    installed (I don't know even what is its purpose) so I can't follow the solution steps.

    Has anyone got any suggestion? Aside for a clean install. Thank you

    Updating to 2004 failure due to 0xc1900101 error

    Hello,

    I'm facing consistent issues updating from 1903 to version 2004 facing a 0xc1900101 error after attempted installations.
    I've uninstalled antivirus, updated graphics drivers, and ran sfc /scannow. There is 144 gb free on my install drive.

    Does anybody have any suggestions? I've been trying this update on and off for a few weeks.

    Windows version is 10.0.18362 Build 18362

    Thanks
