    Have it enabled during last night... This is what happened, and MS diagnostic went crazy today (CPU on 100 for hours...)
    disabled it and went to normal again
    Attachment 184837
    Thanks for sharing this info. I only noticed a significant drop in performance and disabled the thing alltogether. Never bothered to look for any clues.

    The laptop I tried it on, is optimized/configured for long battery life and anything that takes resources I kill immediately.

    Probably either a 3rd party driver issue, or your CPU is just not made for it, or you RAM
    If you GSOD'd use WhoCrashed and post(in code tags) what it lists.
    Here you go.. no third party drivers. Must be my i3-4150 an platform HP Q97 chipset

    Code:
    Crash dump directories: 
    C:\WINDOWS
    C:\WINDOWS\Minidump
    
    On Sun 15. 04. 2018 00:55:19 your computer crashed or a problem was reported
    crash dump file: C:\WINDOWS\Minidump\041518-23796-01.dmp
    This was probably caused by the following module: ntoskrnl.exe (nt+0x112253) 
    Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF8030BA2E57A, 0xFFFF8089609776C8, 0xFFFF808960976F10)
    Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M
    file path: C:\WINDOWS\system32\ntoskrnl.exe
    product: Microsoft® Windows® Operating System
    company: Microsoft Corporation
    description: NT Kernel & System
    Bug check description: This indicates that a system thread generated an exception which the error handler did not catch. 
    This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. 
    The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

    --------------------------------------------------------------------------------
    Conclusion
    --------------------------------------------------------------------------------
    
    2 crash dumps have been found and analyzed. No offending third party drivers have been found. Connsider using WhoCrashed Professional which offers more detailed analysis using symbol resolution. Also configuring your system to produce a full memory dump may help you.
    Diagnostics are still going crazy.. Not so much tho

    your issue seems to be related to CPU since it does not meet the minimum hardware requirement (it should lack VT-d), Virtualization-based Security (VBS)

    But that makes no sense since you are using integrated Intel Graphics, but yeah, in that case to old a CPU for VBS.

    VT-d is something completely different and has nothing to do with VBS. Only requirements are VT-X/AMD-v and virtualization compliant hardware drivers, which all modern hardware should have today. If not, then better switch driver or in worst case hardware since it introduces other threats and issues also.

    UPDATE: Actually now when I read that article it states that it must have VT-d, which another MS article never even mentioned as an requirement nor enhancement. ... MS documents/blogs are very confusing...

    The overall concept behind VT-d is hardware support for isolating and restricting device accesses to the owner of the partition managing the device.


    VT-d, at the time of this writing, includes four key capabilities

    1. I/O device assignment. This feature allows an administrator to assign I/O devices to VMs in any desired configuration.

    2. DMA remapping. Supports address translations for device DMA data transfers.

    3. Interrupt remapping. Provides VM routing and isolation of device interrupts.

    4. Reliability features. Reports and records system software DMA and interrupt erros that may otherwise corrupt memory of impact VM isolation.

    Note that VT-d is not dependent on VT-x. That is, a VT-x enabled system can operate without VT-d, or without VT-d enabled or configured. You simply miss the benefits of the feature. Many people have asked about this point.

    Correct!

    VT-x(even though still seen as a BIOS option) is now just called VT:

    Yep, but this is so confusing now.

    If VBS require VT-d, then why is the button in WD enabled on my computer in the first place? It should be completely disabled or even better, hidden altogether since my hardware does not meet the minimum requirements. On my other laptop I don't even have a TPM chip, so there this feature should definitely be disabled. HAHAH!

    I think MS has a lot to throw back at the drawing board and rethink stuff a bit.


    EDIT: No, what I just said does not apply to Core Isolation since it only protects Core OS code in memory.


    EDIT: Now when I read the description texts in WD, it states that all those features visible under Device Security are enabled, since my hardware supports it. But why on earth is there a button under Security Processor to enable the feature, if it's already enabled? Makes no sense to me.

    There is an unofficial method that is dead simple using wintousb from Windows To Go Creator, Data Recovery, BitLocker Home Edition & PC Utility which works on any version of Windows, even Home.

    It is not exactly the same as Windows To Go as WTG has inbuilt protections if drive is accidentally removed before shutting it down whereas wintousb would just probably crash.
    Hmmmmm, thanks, Cereberus. I'll give that a look too.

    Well I do not think that I will be trying this anytime soon.

    Thanks guys... but why does MS says in settings, that my hardware meets requirements, when it doesn't. Whomever coded that stuff should knows it, and code it right...

    Diagnostic is still consuming 50% of resources, after 3 or 4 hours.. looks I'll have to make image restore after all
