I want to bebuild my system

I've installed and registered my 360 product

I currently have two installations

My system (which I want to rebuild ) and my wifes system

I can't find any info. on preserving my license before blowing away my system

Viewing the Norton Account lists the 3 installation limit, not a usage count

What's the proper practice here from nortons license count prespective ?

Regards
