I was very happy to see a subtle change in the Windows 7 networking configuration settings that validates a static change to TCP/IP settings. By default, If you decide to manually enter any of IP address, Subnet mask, Default gateway, or DNS server address, Windows 7 will do a validation test to make sure what you entered hasn’t broken connectivity. You can easily disable this if you are testing or don’t care to validate the changes.

This subtle change will go a long way for those who have to support their friends and family over the telephone Is anyone really making static changes to their TCP/IP settings these days? Certainly not for casual users.
