We take this responsibility very seriously and take significant steps to enforce our policies and code of conduct in support of human rights, labor, health and safety, environmental protection, and business ethics through our assurance program,” said a Microsoft spokesperson to Windows Central on Monday. “All forms of forced labor are specifically banned by our Supplier Code of Conduct.
