NetSetMan is an excellent Windows tool to have on your computer if you need to change network settings frequently. Going through the Windows network connection dialogs to change the IP or DNS addresses or other settings frequently is a real pain. NetSetMan allows you to maintain six different profiles, each with all possible network settings, and switch between them in a click. I am finding it a boon to switch between DHCP and static IP addresses when I switch my notebook between two different wireless networks.
Tried with: NetSetMan 3.4.5
