Information
This policy setting specifies whether Search Companion should automatically download content updates during local and Internet searches. There is a small risk that users will unknowingly reveal sensitive information because of the topics they are searching for. This risk is very low because even if this setting is enabled users still must submit search queries to the desired search engine in order to perform searches.
Solution
Configure the following Group Policy setting in a manner that is consistent with the security and operational requirements of your organization-
Computer Configuration\Administrative Templates\System\Internet Communication Management\Internet Communication settings\Turn off Search Companion content file updates
Impact- Internet searches will still send the search text and information about the search to Microsoft and the chosen search provider. If you select Classic Search, the Search Companion feature will be unavailable. You can select Classic Search by clicking Start, Search, Change Preferences, and then Change Internet Search Behavior.
