    Hi all,I'm trying to make a VM using Hyper-V on Windows 11 pro with GPU pass-through using DDA. I have followed the steps outlined in this link and have tried this fix with no luck.With the Virtualization Based Protection disabled in the Group Policy editor, System Info still says Virtualization Base Security is Running even after reboot.Thank you in advance for any help.

    A hypervisor feature is not available to the user.

    I got an error on gpupdate /force as below on my workstation which is Windows 10 Enterprise version 1803.

    -----------------------------

    {F312195E-3D9D-447A-A3F5-08DFFA24735E} failed due to the error listed below.

    A hypervisor feature is not available to the user.

    Note: This component only reports overall status information. It does not report information about its individual policy settings; consequently, those settings will not appear in this tool. Please contact the vendor of this component to check if an updated
    version is available.

    -----------------------------

    It is my understanding that hypervisor is feature to install/manage multiple OS in one workstation. Actually I only install one Windows 10 to my workstation. I am not sure it is related to hypervisor or not, but I connect to virtual server from my workstation
    over VMware VSphere, but the virtual server is not installed on my workstation. It is running on other physical servers in the same network.

    The error above is showed up when I executed gpupdate /force on my windows 10 workstation. What kind of action I should take to fix the error? Any advice will be appreciated..

    Can't Update/Disable/Uninstall PCI Express Root Port

    I suspect that this problem is unique to this specific computer.

    After 8 or 9 attempts to install Feature Update 1903, I decided to check for out-of-date drivers and Restore Health etc. (I have several other computers and they generally recover after 2 or 3 attempts.) When I attempted to Update the PCI Express Root Port,
    it seemed to find an updated driver, but seconds after the installation began the CPU light went out, the keyboard and mouse froze and I had to reboot. The information on the screen froze. The same thing happened when I tried to Disable the device, or when
    I tried to Uninstall the device. Typically 1903 fails around the 89% Updates phase and then it recovers the previous installation.

    If at that point during the Microsoft installation, an attempt is made to scan for obsolete drivers, my system will definitely crash. Possibly this is the reason that 1903 won't install.

    Of course you will ask what the error message was. Well this time it told me that 1903 just required a reboot to be successful. This was obviously a faulty message because it previously said that it was restoring my previous system. Here is a list of attempts:
    Requires Restart to finish installation; Failed to install 0xc1900101; Failed to install 0x8007001f; Requires Restart; Requires Restart; Requires Restart; Failed to install 0x8024200d; Requires Restart; etc.

    Gateway DX4850-43c; Intel Core i5-2300 CPU @ 2.8 Ghz; Ram 6 Gb; 64 bit, X64 Processor; Windows 10 Home 1809 installed 2019-02-17; OS Build 17763.737.

    Anyone have any ideas on how to freeze my system and stop these constant downloads, or destroy the PCI Express Root Port?
