To grow the developer community, SIG Windows  released multiple [tools](https://github.com/kubernetes-sigs/sig-windows-dev-tools/). The new tools support multiple CNI providers (Antrea, Calico), can run on multiple platforms (any vagrant compatible provider, such as Hyper-V, VirtualBox, or vSphere).

* fix issue: fail to detach azure disk when there is server side error ([#74398](https://github.com/kubernetes/kubernetes/pull/74398), [@andyzhangx](https://github.com/andyzhangx))
* Fix keymutex issues which may crash in some platforms. ([#74386](https://github.com/kubernetes/kubernetes/pull/74386), [@danielqsj](https://github.com/danielqsj))

    * EBS on AWS, and Cinder on OpenStack). In previous versions of Kubernetes
    * a PersistentVolumeClaim without a StorageClass annotation on these cloud
    * platforms would be satisfied by manually-created PersistentVolume objects.
    * Administrators can choose to disable this behavior by deleting the automatically

    * While this is a backwards-incompatible change, it would have been impossible to setup reliable monitoring around these metrics since the labels were not stable. 
* Fix keymutex issues which may crash in some platforms. ([#74386](https://github.com/kubernetes/kubernetes/pull/74386), [@danielqsj](https://github.com/danielqsj))
