    W10 1809 - Hyper-V doesn't work anymore after upgrade from 1803 (VT-d)


    Hello,

    unfortunately I decided to upgrade from Windows 10 1803 to 1809.
    The upgrade did fail everytime. (Error-Code: 0xC1900101 0x40017)

    After hours of troubleshooting, analysis of setupact.log and looking for answers on the web I did find the following solution: Link
    It is german, but the user had the same problem and it was solved by disabling Hyper-V.
    I did disable/uninstall the Hyper-V role/function and the upgrade to 1809 was finally successful.

    I did not install Hyper-V just for fun in the past and I did try to enable it again in 1809. The activation of the role needs a reebot.
    The reboot was NOT successful and Windows did NOT start anymore.

    After doing research on a second computer I did stumble over problems regarding the "VT-d" technology:


    - PSA: Disable VT-d in your BIOS if Windows 1803 fails to update and is stuck on the blue logo : windows
    - Windows 10 1809 bereitet Probleme bei der Installation Tipps und Tricks Deskmodder Wiki
    - Can't boot with Intel VT-D enabled, since build 17025

    -

    I did disable VT-d in BIOS/UEFI and Windows 10 1809 did finally start.
    Of course Hyper-V does NOT work without VT-d and now I am fu****

    The BIOS/UEFI is on latest Version of the vendor.
    I did install latest 1809 cumulative update from yesterday. I did try to disable some of the new security-function of the OS, but this did NOT help either.
    My CPU is AMD X6 and AMD 870 chipset.

    I did a roll-back to 1803, because I need Hyper-V.

    What could I do to get this fixed?
    What could I do to inform Microsoft about it more directly?

    Thank you

    Intel Virtualization Enabled in BIOS causes Win"duh"z 10 to hang/stop on boot.

    A couple months ago I noticed that my vmware no longer runs.
    Like many I did the October update (1809) for Windows 10.
    Before that it all worked!

    Another app, AMIDuos reported that virtualization is off.
    So I checked in the BIOS and for some reason virtualization was off.
    So I turned it on.
    Windows 10 would never boot.
    So I turned it off.
    I noticed that my coreI 7 6700 CPU with hyper threading showed suddenly only 4 "cores". Never happened before.
    With VT-d enabled it showed again 8 "cores".

    In my case I can pin point the following:
    My current built is Version 10.0.17763 Build 17763. Before that all this was not a problem.
    Now after the upgrade:
    VT-d "ENABLED": no problem
    Intel Virtualization "ENABLED": Windows hangs on boot. No go. only in Safe mode.
    So no apps that require/run on virtualization will run, e.g. AMIDuos, vmware etc.

    You call that an "improvement?" Micro$oft?
    I call that a disaster! hindrance, impediment, decay, declension, degeneration, deterioration, diminishment, downgrade, worsening, disablement etc. Gross incompetence as you just proven with the October 2018 update and the vanishing files!

    As the Germans say: "Verschlimmbessern". (To make worse by "improving")
    The American equivalent would be: "If it ain't broken don't fix it"

    SO MICRO$OFT, WHEN WILL YOU BECOME A COMPETENT BUSINESS NOT DELIVERING "UPDATES" WITH MORE BUGS AND DEFICIENCIES? WHEN WILL YOU STOP DELIVERING DEFECTIVE SERVICES AND PRODUCTS!?!?!?

    I'M SO GLAD YOU ARE NOT BUILDING CARS, TRAINS OR PLANES! WE'D ALL BE DEAD BY NOW, COURTESY YOUR BLOATED GARBAGE OS WINDOWS 10!

    GODDAM-IT! REALLY!
