    Windows Sandbox error 0x800736b3 when launching


    When I try and launch Windows Sandbox, I get this:

    Windows Sandbox error 0x800736b3 when launching e79cf673-ad06-46d5-bce4-6f67d6bc76f1?upload=true.png

    I have Hypervisor, Sandbox, and Virtual Machines enabled in Windows Features.

    I haven't seen anyone get this same error. I am using Windows 10 Pro on an insider preview.

    Error 0x800736b3 when installing KB4074588

    Hi,

    The 0x800736b3 appears to be linked to .NET Framework 3.5.

    I suggest you to follow the below steps to check whether the .NET Framework 3.5 has been installed or not.

    • Press Windows+X and then select programs and features.
    • On the left hand side click on the option turn windows features on or off.
    • Check whether the “.NET Framework 3.5” has been checked or not.
    • If not check then I suggest you to check it and then install it.
    • Restart your computer and try installing the KB4074588 again.

    Kind regards,

    Leon

  3. error ox800706d9 sandbox not work

    For Windows 10 1903 sandbox wont start errors all you do is just restart the following service under Administrative tools



    Container Manager Services.



    then reopen sandbox should start up like normal.

    If it does not start up do the following below.



    If you have Hyper-V installed and Virtual disk is turned on under Administrative tools you must restart all these services



    1. Container Manager Services
    2. HV Host
    3. Virtual Disk
    4. Hyper-V Virtual Machine Manager
    5. Hyper-V Host Compute Service
    6. Network Virtualization Service

    Do this in the following order

    1. Right click over (Network Virtualization Service) click restart and wait.
    2. Right click over (Virtual Disk) click restart and wait.
    3. Right click over (Hyper-V Virtual Machine Manager) click restart and wait
    4. Right click over (Hyper-V Host Compute Service) click restart and wait
    5. Right click over (Container Manager Services) click restart and wait



    Check these services are still on

    Application Guard Container Service (If installed)

    Remote Procedure Call (RDC) (""This must be running as most of the others rely upon its function it should never be disabled"")



    Once they are checked start sandbox and it should open up if it does restart your computer to ensure the services are still functional are a restart of computer this should also be done if sandbox does not start up once these services are restarted
    and checked.

    Well I work out a solution to get Windows Sandbox going again it’s not the best solution but work around follow the steps below and hope it works for all of you guys.



    1. The first thing you have to do is turn off Windows Defender Random Folder Protection
      or the anti virus random folder protection.
    2. Next turn off Windows defenders Tamper protection Or the Anti-Virus Tamper protection
    3. Once that turn off Go to Control Panel open it
    4. Location Administrative Tools
    5. Next head to Services and open that
    6. Scroll down to Container Manager Services
    7. Turn off Container Manager Service only
    8. Leave service screen open but minimize it
    9. Next go to control panel location and open File Explorer Options
    10. In File Explorer Options Untick the following:



      • Don’t Show Hidden Files, Folders, or Drivers
      • Hide Empty Drivers
      • Hide Extensions Known Files Types
      • Hide Merge Conflicts
      • Hide Protected Operating Systems Files



    1. Now move File Explorer Options to one side of your screen
    2. Go back to Control Panel
    3. Locate and open Program and Features
    4. Go to Turn Windows Features on or Off
      open it

    5. Scroll down to Windows Sandbox
    6. Untick Windows Sandbox
    7. Click ok to uninstall Windows Sandbox
    8. Close off only the screen that removed Windows sandbox
    9. Next go to your main drive usually C: Drive
    10. Location ProgramData
      • We need to get to this location (C:\programData\Microsoft\Windows\Containters\Sandboxes)



    1. Even open it or expand ProgramData
    2. Locate Microsoft open it or expand
    3. Scroll down to Windows open it or expand
    4. Now go to the folder called Containers
      open it or expand
    5. Now you should see Sandboxes
      • You Should be at this location Now

    (C:\programData\Microsoft\Windows\Containters\Sandboxes)



    1. Now in that folder Sandbox is folder that looks like this



      • 4040f074-2ff6-471c-9f38-4836db85fff6
      • Inside it is sandbox.vhdx



    1. What we need do is delete all the strange folders keys that’s in

    (C:\programData\Microsoft\Windows\Containters\Sandboxes)



    1. If it does not delete just wait a few seconds and try again



    Caution do not delete the folders from recycle bin yet



    1. Next go to the folder below it called
      Zygotes




    (C:\programData\Microsoft\Windows\Containters\Zygotes)



    Repeat the steps you did at Sandboxes and delete the strange folder keys with its contents but do not delete what’s in recycle bin.



    1. Repeat the step you did at Sandboxes and delete the
      strange folder key with its contents

    2. If it does not delete just wait a few seconds and try again
    3. Now move the open explorer screen to one side of the screen
    4. Head back to control panel
    5. Locate and open Program and Features
    6. Go to Turn Windows Features on or Off
      open it

    7. Scroll down to Windows Sandbox
    8. This time re-tick Windows Sandbox and close and allow it to reinstall the sandbox
    9. Close only the install screen
    10. Go back to services and Restart Container Manager Service
    11. Leave Services screen open move it to once side again.
    12. We now head to Start then Settings
    13. Scroll until you find Windows
      Sandbox click it twice.
    14. Wait and see how the screen opens if it give you another error
      repeat this process
    15. When you open Windows Sandbox it should
      hang for 5 to 10 minutes without any error message
    16. What it’s doing is rebuilding its image then it opens back to what it was in default settings.
    17. Once you have sandbox reopened and its got the icons load close it pressing the
      red X
    18. Then reopen Windows Sandbox to see if it opens up again.
    19. If it does you fixed it.
    20. Now we can turn back on
      • Windows Defender Random Folder Protection
        or the anti virus random folder protection



      • Windows defenders Tamper protection Or the Anti-Virus Tamper protection



    1. Retest Windows sandbox will open again with the above
      turned on
    2. If it does the next thing is to restart your computer and
      Repeat the opening of Windows sandbox.
    3. Once all is well your right to continue
    4. You can delete the folders in your recycle bin too.
