What does this do?

Turning off all of these settings and only keeping "Internet Protocol Version 4 (TCP/IPv4)" checked... will do what generally? (Compared to having them all checked)

Clients for Microsoft networks:
Provides application layer services that enable programs to access shared file and printers on the network.

QoS Packet Scheduler:
Enables the network clients to prioritize network traffic based on bandwidth available and changing network conditions.

File and Printer Sharing for Microsoft Networks:
Enables the computer to share its files and printers with other users on the network.

Link-Layer Topology Discovery Mappers I/O and Link Layer Topology Discovery Responder:
Implement the protocol that enables Windows 7 to compile a map of the computers on the network.

With out them check you cant do the things posted above.

You forgot to mention what IPv6 is used for.

The Argument against Disabling IPv6.

It is unfortunate that some organizations disable IPv6 on their computers running Windows Vista or Windows Server 2008, where it is installed and enabled by default. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true.
From Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Moreover, applications that you might not think are using IPv6—such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail—could be.
Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.

Its a good thing too. I learned something from your post.

Can't rep you but thanks.
