Disable all direct connections to Zoom web service

Zoom 5.17.5

Supported on: Microsoft Windows XP SP2 or later

Description

Default policy is false. If this setting is true, client will disable the direct connection to Zoom web service. If this setting is false, client will always try direct connection even there is proxy server configuration. If this policy is not set, client will use the default setting.

Registry

HKLM Software\Policies\Zoom\Zoom Meetings\General

Value name: DisableDirectConnection2Web

Enabled: DisableDirectConnection2Web = 1

Disabled: DisableDirectConnection2Web = 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.
