Hardware changes are cumulative. Many things can cause Windows to think
something has changed. A BIOS upgrade may cause Windows to see a couple of
changes if you have an on board NIC and video. A driver change can cause
Windows to think that the hardware changed if the driver includes a firmware
update. What this means is that over time Windows may see hardware changes
even if you haven't actually changed any hardware. Each time it sees a
change a counter is incremented when the counter hits x number of changes
you see the activation screen. What x equals and how the hardware changes
are weighted is only known to Microsoft. Microsoft changes these factors
when based on what they see happening.
Having to re-activate is a nuisance but it isn't usually a problem. At worst
you may have to phone a toll free number. I'd go ahead and install the hard
drive then re-activate.
