Windows 10: Is it safe to delete baselayer and sandbox from Containers Folder

First post. Hello everyone and Happy New Year.
I made the mistake of following the tutorial to enable Sandbox. It failed miserably, with different errors at different times such as the common Error: 0x80072746.

So I disabled Sandbox but i still have this garbage partition sitting there with 8GB allocated. For those who had success disabling Sandbox to remove this partition (portablebaselayer), good for you. This does not work on my system, despite turning off all relevant features such as VMP and even containers.

After googling for hours I found a link to vhdx files and i did a search using WiseJet.
My question. Is it safe to delete vhdx files linked to Sandbox and baselayer? I don't use containers.
examples of the many related folders with vhdx files:

C:\ProgramData\Microsoft\Windows\Containers\Sandboxes\a7a6c2d7-f74d-4386-91b0-b2c683d1cdd2\sandbox.vhdx

C:\ProgramData\Microsoft\Windows\Containers\BaseImages\0cd2da3a-d34b-4084-bfa5-ef3781acf177\baselayer.vhdx

I'm hoping deleting these files might finally allow me to get rid of this garbage partition.

And for those who think this partition is related to Sandbox, NOPE, not on this home system.

Windows 10 Home
Version 1903
Build 18362.592

Trouble deleting a folder

Thanks for the suggestion but it says "delete folder failed for E:\....." for each folder I try.

*Confused

Will I be forever stuck with these unnecessary folders? *Oh Well hwell:

 

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:
    

1. • 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
   

1. • 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
      

1. • 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.

Unable to delete a folder - Invalid folder name


Suggestion:

1. Run chkdsk x: /r to make sure that there's no HD corruption.
   x: is the drive containing the folder you want to delete.
2. Try to delete the folder again. If still does not work, go to step 3.
3. Download: Download - Linux Mint and create a bootable USB using: Rufus - Create bootable USB
4. Boot up with Linux Mint and try to delete the folder again.
   NOTE: Unlike WinPE. Linux does not have any Windows permission imposed to it so it is easier to delete.
