Recently I have installed office 2010 std edition with genuine license key which i got it from net. Unfortunately I lost my key somewhere in my mail box and do remember starting few characters of my key (CXXXX-XXXXX-XXXXX-XXXXX-XXXXX). I just want to transfer my license by installing the same on my laptop. Is there anyway i can recover my license from existing PC? I do explored retrieving key using few key finder's available on net. But they are retrieving altogether different key (VXXXX-XXXXX-XXXXX-XXXXX-XXXXX) and and am not able to activate using retrieved key. Can anyone help me how to retrieve/recover my key from installed software ??? Thanks in advance.
