Windows Firewall

The Windows Firewall (MpsSvc) service helps to protect the computer by preventing unauthorized users from gaining access to the computer through the Internet or a network. For an overview of the changes in Windows Firewall in Windows 7 and Windows Server 2008 R2, see What's New in Windows Firewall with Advanced Security.

This service is installed by default and the startup type is Automatic.

When the Windows Firewall service is started in the default configuration, it logs on by using the Local Service account.

The Windows Firewall service is dependent upon the following system components:

  • Base Filtering Engine
  • Remote Procedure Call (RPC)
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
  • Windows Firewall Authorization Driver
