Configure allowed extensions - GPO format and examples

https://code.visualstudio.com/docs/setup/enterprise#_configure-allowed-extensions

Intune is currently unable to import GPO correctly due to a microsoft limitation

Looking at the documentation there is not much about how to configure the registry entry to allow or deny extensions, nor is there much on same for update.

There are no example registry entries and no hints as to the formatting to use for registry entries.

Theres a lot about how to configure the JSON settings for individual install but nothing on how to add to Intune via script or to configure the GPO manually

Ideally the format of what needs to get into something like a Reg Add command such as;

reg add "HKLM\SOFTWARE\Policies\Microsoft\VSCode" /v AllowedExtensions /t REG_SZ /d {"ms-vscode.powershell":true,"microsoft":true}

or a Powershell equivalent

Start with the linked Configure allowed extensions documentation and review its existing GPO and update-setting guidance. Add registry-entry formatting and concrete Reg Add or PowerShell examples for manual GPO and Intune setup; done means administrators can configure allowed or denied extensions and updates without guessing the value format.
