Limits the number of user data snapshots retained for use in case of emergency rollback

Following each major version update, Microsoft Edge creates a snapshot of parts of the user's browsing data to use if there's a later emergency that requires a temporary version rollback. If a temporary rollback is performed to a version for which a user has a corresponding snapshot, the data in the snapshot is restored. This restoration lets users retain settings such as bookmarks and autofill data.

If you don't configure this policy, the default value of 3 snapshots is used.

If you configure this policy, old snapshots are deleted as needed to respect the limit you set. If you set this policy to 0, no snapshots are taken.
