Huawei laptops return to Microsoft’s online store after mysteriously disappearing - The Verge
Microsoft has been mummed about the issue before, perhaps, they are trying to observe public response regarding the ban by Trump.

There are negative feedbacks regarding the ban, and Microsoft is still in that area where they're still undecided with Huawei.
