CCleaner does not clean the list of URL/IP addresses stored in
HKEY_CURRENT_USER\Software\Microsoft\RAS Autodial\Addresses
when the "Auto connection manager" service is not disabled.
From msdn:
AutoDial Mapping Database
The AutoDial mapping database maps network addresses to RAS phone-book entries. The database can include IP addresses (for example, "172.21.167.35"), Internet host names (for example, "www.microsoft.com"), or NetBIOS names (for example, "products1"). Associated with each address in the AutoDial database is a set of one or more RASAUTODIALENTRY entries. Each of these entries specifies a phone-book entry that RAS can dial to connect to the address from a particular Telephony Application Programming Interface (TAPI) dialing location. For more information about TAPI dialing locations, see the TAPI documentation.
AutoDial automatically creates entries in the AutoDial mapping database in two situations:
- When an attempt to connect to a network address fails
If there is no entry for the address in the mapping database, and the computer is not connected to a network, either directly or through RAS, AutoDial prompts the user to specify the information necessary to establish a dial-up connection. If the user provides the information and the dial-up connection operation is successful, AutoDial stores the information in the mapping database.
- When the computer is connected to a network through RAS
Whenever the user connects to a network address, AutoDial creates an entry in the database. The entry maps the network address to the phone-book entry that was used to establish the RAS connection.
