Recently I tried to run a setup program into the Windows Sandbox, but Windows Defender blocked it.
About 60 seconds later, I discovered that I cannot disable/configure it from the usual UI.
After some investigation, I discovered that we can do it by a couple of commands in PowerShell with administrative access rights:
- Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Control\CI\Policy” -Name “VerifiedAndReputablePolicyState” -Value “0”
- CiTool.exe -r
After applying these changes, the setup program is no longer blocked.
