    Windows 10 Pro 1909 upgrade to 2004 or 20H2 freezes at 48% 0xC1900101


    Hi,

    I am a new member and have signed up as I am pulling my hair out trying to figure this out for the past few months.

    I currently have Windows 10 Pro 1909 installed and Windows update has tried to install Windows 2004, however whilst installing on reboot it freezes at 48%. I have also tried previously to install 2004 with an ISO mounted and USB however with no luck.

    Also I have tried installing Windows 20H2 both with ISO and with USB and again it just fails and freezes at 48%.

    I have attached the error message I receive i have to force shutdown (once it freezes) and it rolls back any changes.

    Please can anyone help

  3. 0xC1900101 - 0x30018 Windows 10 upgraded from 1909 to 2004 error code

    If these are one of your code. I have successfully upgraded from Windows 10 Pro v1909 to v2004 as the error has been resolved. Microsoft techicial guy has spend hours try to resolved mine via CMD fixes but no successfully. I have spend hours trying to think
    what should I do to avoid rollback to 1909 when upgraded stuck at 60% during final set up.

    What I did to resolved this is doing this step:

    Download Windows 10 v2004 here: Download Windows 10 via download tool now. Saved that ISO on your desktop.

    Go to control panel, programs, under programs and features click turn windows features on or off (disabled all of it and apply ok) reboot pc

    Click ISO to open in windows explorer and click setup

    It's will installing your windows 10 2004 upgraded and wait until it completed successful.

    When it all done and your windows 2004 has successful upgraded from 1909 go back to control panel, programs, under programs and features click turn windows features on or off (enabled some of it if you need it or all of it and apply ok) and reboot pc.

    All done!

    The main issues failed with 0xC1900101 - 0x30018 Windows 10 upgraded from 1909 to 2004 was caused by Windows Features was enabled.

    1909 to 2004 upgrade

    The 20H2 iso is available for download (see News section), so that naturally 'includes' 2004. This is a step preceding 20H2 becoming available by Windows Update in place of 2004; presently you'd be offered 2004 by WU then the 20H2 enablement package. All downloads are available following the relevant article in the News section.

    It's an evolving scenario following the pattern of 1903/1909.
