For those who don’t know their CPU has more than 14 cores, on https://ark.intel.com/ you can find specifications for all Intel CPUs. AlakaLazlo, your i7-5820 is a 6 cores / 12 threads CPU, so it’s not affected.
@Rommelar: We contacted the relevant parties at MS - we decided to inform the users because no short-term solution has been found.
