Store any leftovers in a covered container in the fridge. Stored properly, leftovers will last for 3 - 4 days in the fridge. Much like any leftover pasta, the texture of this cream cheese pasta will get drier the longer it sits in the fridge. Therefore, my favorite way to reheat the pasta is to gently warm it in a small pan over low heat, covered with a lid. Before adding the lid, stir in a few tablespoons of milk to the pasta to help the sauce reconstitute. Although I have recommended freezing some of my recipes that contain dairy (such as this recipe for red skin mashed potatoes), I don't recommend freezing this pasta recipe. Cream cheese tends to get grainy when frozen and thawed, and the silky smooth sauce is pretty much what this recipe is all about. Therefore, I think it's just not worth it to try and freeze this pasta. Trust me, this dish is so good, you're not likely to have many leftovers!
