Warning

This policy is currently in preview mode only and will be supported in future releases. It may be used for testing purposes, but should not be used in a production environment at this time.

This policy controls the inclusion of Edge tabs into Alt+Tab.

Enabling this policy restricts the number of Edge tabs that are allowed to appear in the Alt+Tab switcher. Alt+Tab can be configured to show all open Edge tabs, only the 5 most recent tabs, only the 3 most recent tabs, or no tabs. Setting the policy to no tabs configures the Alt+Tab switcher to show app windows only, which is the classic Alt+Tab behavior.

This policy only applies to the Alt+Tab switcher. When the policy is not enabled, the feature respects the user's setting in the Settings app.

Tip

This is an ADMX-backed policy and requires a special SyncML format to enable or disable. For details, see Understanding ADMX-backed policies.

You must specify the data type in the SyncML as <Format>chr</Format>. For an example SyncML, refer to Enabling a policy.

The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.
