If I understand you correctly, you were asking about how to extend a trial period or to reset the trial, yes you can do that if you know what you are doing, and there is an automatic tools for that (to reset trial period) however it's illegal and it's considered as piracy, my advice..stay away from those tools, better using open sourced softwares or the free one.
