This setting controls the inclusion of app tabs into Alt+Tab.

This can be set to show the most recent 3, 5 or 20 tabs, or no tabs from apps.

If this is set to show "Open windows only", the whole feature will be disabled.

Warning

This policy is currently in preview mode only. It may be used for testing purposes, but shouldn't be used in a production environment at this time.

Enabling this policy restricts the number of Microsoft Edge tabs that are allowed to appear in the Alt+Tab switcher. Alt+Tab can be configured to show all open Microsoft Edge tabs, only the five most recent tabs, only the three 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 isn't enabled, the feature respects the user's setting in the Settings app.
