Currently I am using a dynamic dns updater software on Windows, but to keep it updating I have not to close it, also the software is not able to run at backgoud, I searched on google but the answer became complicated since there are many details to pay attention to, free, not free, installed on machine, configured on router, trusted, not trusted ...
So please help me find a trusted free dns updater for Windows which can run as service, and maybe which can send email when update fails.
