How to flush dns in windows 7 or windows 8?

In all OS(operating systems) dns data is cached which is provided by DNS server (IP Address /DNS details), this is required to increase the dns lookup for the subsequent request to the same domain/hostname. In some cases you will see error page or invalid host page for a given host. This can be because the dns details cached at your computer is not valid anymore. So in that case you need to clear dns cache. There are commands available in each OS. These command clears the cache and then next time dns client will get the latest data from dns server.(when the next request triggers)
