There is no defininitive answer to your question. If you change your
hardware at some point you will be required to re-activate. Hardware changes
are cumulative. If you change one thing now then three months from now
change another thing, or even the same thing again this will be two total
changes. Some things that may cause Windows to think there has been a
hardware change are BIOS updates and driver updates that change the device
firmware. This means if you have done a couple of BIOS updates, then updated
a device driver that reprograms the firmware, then add some RAM an update
may be triggered even though the only physical change was to add some RAM.
It can be very confusing trying to figure out if a change will require
re-activation. Fortunately it doesn't really matter. As long as you are
within the terms of the EULA the worst that will happen is you may have to
phone to get Windows activated.
