1.1.31 Ensure 'Clear cached images and files when Microsoft Edge closes' is set to 'Disabled'

Information

This policy controls whether cached images and files are deleted each time Microsoft Edge closes.

Note: If this policy is disabled, do not enable the ClearBrowsingDataOnExit policy, because it will take precedence over the ClearCachedImagesAndFilesOnExit policy and will delete all browsing data when Microsoft Edge closes, regardless of how the ClearCachedImagesAndFilesOnExit policy is configured.

The recommended state for this setting is: Disabled.

Rationale:

Deleting browser data on close will delete information that may be important for a computer investigation and investigators such as Computer Forensics Analysts may not be able to retrieve pertinent information to the investigation.

Impact:

Cached images and files will not be deleted on closing and the user will be unable to change this setting.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled

Computer Configuration\Policies\Administrative Templates\Microsoft Edge\Clear cached images and files when Microsoft Edge closes

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MSEdge.admx/adml that can be downloaded from Microsoft here.

Default Value:

Not Configured - But users can choose whether cached images and files are cleared on exit.
