This issue occurs due to a workaround for the outdated Windows AMI (not updated as per https://github.com/apache/incubator-mxnet-ci). Improvements to the workaround that avoid this flakyness are welcome.
In the meantime @josephevans and @larroy are working on updating the Windows AMI which will obsolete the flaky workaround.
