While the ssd is "easily" replaceable(once you get to it), the RAM is NOT. It is soldered onto the motherboard. Unless you want to try your luck with soldering gun and small 2 to 4gb RAM chips...
If this is not a troll question, don't attempt this yourself. You have much to learn before attempting to replace SSDs on a screw-less device. I suggest building your own tower PC first. There is only one permanent storage drive on this device, so Windows will necessarily be installed on there.
To more clearly answer your question, you could either attempt an image level copy of the drive or yes, reinstall windows.
