Extensions that connect to one of these origins keep running as long as the port is connected. If unset, the policy's default values are used. These are the app origins that offer software development kits (SDKs) that are known to not offer the possibility of restarting a closed connection to a previous state: - Smart Card Connector - Citrix Receiver (stable, beta, back-up) - VMware Horizon (stable, beta) If set, the default value list is extended with the newly configured values. The defaults and policy-provided entries grant the exception to the connecting extensions as long as the port is connected. Example value: chrome-extension://abcdefghijklmnopabcdefghijklmnop/ chrome-extension://bcdefghijklmnopabcdefghijklmnopa/

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
