Do not add shares from recently opened documents to the My Network Places folder
User Configuration\AdministrativeTemplates\Desktop
Description
Remote shared folders are not added to My Network Places whenever you open a document in the shared folder.
If you disable this policy or do not configure it, then when you open a document in a remote shared folder, the system adds a connection to the shared folder to My Network Places.
If you enable this policy, shared folders are not added to My Network Places automatically when you open a document in the shared folder.
