Registry

HKLM Software\Policies\Zoom\Zoom Meetings\General

Value name: Disable3rdModuleVerify

Enabled: Disable3rdModuleVerify = 1

Disabled: Disable3rdModuleVerify = 0

REG Builder

BETA

Configure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.

These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
