Obviously with two systems only seeing 1gb of memory apiece the 32bit Windowss would be the best move for each of those. But even for the 32bit 7 you will want to consider upgrading the ram to 2gb for a more stable smoother installation on those two machines.
That extra gig is worth the effort since even back with XP moving up from 1gb to 2gb made a vast difference in overall system stability and performance. This would be something to consider later since memory prices have come down considerably.
To my understanding you only get one product key. That single key can be used to activate either the 32 bit or 64 bit. Once the key is used then that key is linked to that bit choice otherwise I would be able to install 2 products on 4 different PC's.
My concern is I have an older PC that is not going to run the 64 bit. My plan is to just install the 32 bit version and someday when I buy a new computers I can simply uninstall the 32 bit bit from the old computer and then reinstall the 64 bit with the same key on the new computer. I just don't know if Microsoft will let me without calling them first. I am confident that if I needed to call them it would not be an issue.
Does that make sense.
