When asked about the lack of Huawei laptops in the store, an assistant said this was "because of the operating system issue for it".
A number of laptops from Huawei run Windows, the most widely used computer operating system by far, with a Web search throwing up at least four models that offer Windows Home.
iTWire has sought comment from Microsoft as to whether the company will restrict Huawei from using Windows in order to comply with the American Government order. The company said it was declining the chance to comment at this stage.
On Tuesday, the Commerce Department said the ban was being eased for 90 days to enable existing users of Huawei devices to avail of updates.
Huawei, which is now the second biggest smartphone vendor globally after Samsung, uses a customised version of Android on all its smartphones and tablets.
iTWire has also contacted Huawei for comment.
