When you buy new PC these days, it usually come with trial period (60 days) of bundled softwares including Norton Internet Security software.

60 days trial days expired couple of months ago and Norton Security software quit working as they want me to purchase their software which I refused.

Over the holidays, I reinstalled Window7 on my PC and it re-activatre Norton software for another 60 days. I wonder how many times I can reinstall windows and get free Norton software after 60 days is up

The trick is not to registor the software with Norton web site when the registration window pop up once in a while.
