Set to disable Zoom Apps for users who are not authenticated

Zoom 5.17.5

Supported on: Microsoft Windows XP SP2 or later

Description

Default policy is disabled. This policy works independently of old flag 'DisableZoomApps'. If this policy is enabled, client will disable Zoom Apps for users who are not authenticated. If this policy is disabled, client will enable Zoom Apps for users who are not authenticated. If this policy is not set, client will use the default setting.

Registry

HKCU Software\Policies\Zoom\Zoom Meetings\General

Value name: DisableZoomAppsGuestAccess

Enabled: DisableZoomAppsGuestAccess = 1

Disabled: DisableZoomAppsGuestAccess = 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.
