Installing Microsoft Office 365 Home Premium again on same computer after deleting everything

[Mate]

Hi

I had a virus which mad me delete everything and re-install windows again. I had Microsoft Office 365 installed on it previously and now it is asking me for a product key to activate Microsoft Office again.



I bought the Microsoft Office 365 1 Year Premium Package and I am allowed to use it on 5 PCs or Macs. I am wondering if I enter the product key to activate Microsoft Office 365 into the same computer (I had it installed into before before restored Windows again) will it take up another 1 of the 5 uses of the package. Or will it the product key recognise that this is the same computer I used the product key on before and not take up another 1 of the 5 uses again.
