Norton Internet Security 2010 Performance Pack 3PC License Questions...

Hi,

 

I've just install NIS 2010 Performance Pack (NIS+Utilities) onto one of my (two) desktop PCs and see that, in my norton account, it shows that I have "Activations remaining" for "2 PCs" left.

 

How are these 'activations' measured, what does it mean by a 'PC', and how is multi-boot handled?

 

What happens if I need to re-install Windows and/or NIS?

Do I need to 'de-activate' NIS first?

If so, what happens if I can't boot into Windows?

 

Also, does the "3 PCs" apply to just NIS or both NIS and Norton Utilities?
