Fixed with 27766 Workaround for “Your organization used App Control for Business to block this app” dialog in the Canary Channel

After updating to Build 27764 in the Canary Channel, some Windows Insiders are reporting hitting the issue that previously impacted the Dev Channel where an “Your organization used App Control for Business to block this app” dialog is shown when attempting to use or install certain third-party apps on your PC due to an incorrect policy being enforced. The following steps should mitigate the issue:

  1. Open Command Prompt with administrator privileges.
  2. Type and hit enter: mountvol s: /s
  3. Type and hit enter: del S:\EFI\Microsoft\Boot\cipolicies\active{8E8A94F0-6EB9-42C7-A189-E018C8CF3D10}.cip
  4. Type and hit enter: del S:\EFI\Microsoft\Boot\cipolicies\active{36D62F7C-AB85-4F61-8724-744294F24023}.cip
  5. Type and hit enter: del S:\EFI\Microsoft\Boot\cipolicies\active{66D7D265-7EDD-47DD-86E4-F7C42CD55A8F}.cip
  6. Then reboot your PC.

If you are dual-booting between the Canary Channel and the Dev Channel or another version of Windows, you will need to do this workaround BEFORE booting to the other OS.

If the above steps do not work, you may need to disable Secure Boot first and follow these steps:

  1. Disable Secure Boot on your PC.
  2. You will be asked to enter your BitLocker recovery key.
  3. Log in to your PC and open Command Prompt with administrator privileges.
  4. Type and hit enter: mountvol s: /s
  5. Type and hit enter: del S:\EFI\Microsoft\Boot\cipolicies\active{8E8A94F0-6EB9-42C7-A189-E018C8CF3D10}.cip
  6. Type and hit enter: del S:\EFI\Microsoft\Boot\cipolicies\active{36D62F7C-AB85-4F61-8724-744294F24023}.cip
  7. Type and hit enter: del S:\EFI\Microsoft\Boot\cipolicies\active{66D7D265-7EDD-47DD-86E4-F7C42CD55A8F}.cip
  8. Reboot your PC once with Secure Boot still disabled.
  9. Then reboot again and enable Secure Boot.

In small cases, your PC may not boot into Windows. To get out of this state, you can follow these steps:

  1. Disable Secure Boot on your PC.
  2. Then get into Windows Recovery, choose advanced boot options and disable driver signature enforcement.
  3. Then do the above-mentioned workaround for deleting the policies after logging in.
  4. Alternatively, you can also delete the above-mentioned policies directly from the Windows Recovery console.

    después de mountvol s: /s

    s:

    el sistema no puede encontrar el controlador especificado

    Looks like on your command you are missing the space before /s, it may be mounted with a different letter.

    Reboot and try again with the space after S:

    moutvol S: /s

    Your screenshot is missing the space.

    This one works:

    Thanks for your solution, Having got my system up and running a number of very strange problems have arison which were,'t there before the "Organisation block" problem, all intermitant and sometimes all is normal.

    1. If in Windows Explorer I select a sub folder it will jump back to the main folder, this repeats if I try again so I cannot work in the sub folder.
    2. When using a mouse to select an option or a selection the click returns an error sound but does not complete eventually after several tries it completes.
    3. Using a mouse sometimes the cursor stutters, slows or stops
    4. The most annoying thing that these problems are showing on my OTHER PCs including a brand new Asus Zenbook S16 . I thought it might be the mouse but I have three mice and they all produce the same problems????

    HELP

    Can you display the device manager status when it fails and see if there is any error with the drivers?
