In a large pot over medium-high heat, bring water and salt to a boil. Add in pasta and let cook until al dente, about 6 minutes. Reserve 1 cup pasta water, then drain pasta and set aside.
Return pot to low heat. Add in ½ cup reserved pasta water and cream cheese, whisking until smooth, about 2 minutes. Add in cooked pasta and toss in sauce to coat evenly. If a thinner sauce is desired, gradually add in remaining pasta water until ideal consistency is achieved.
