### Windows support improved

- [Performance dashboards](http://perf-dash.k8s.io/#/?jobname=soak-tests-capz-windows-2019) added support for Windows
- [Unit tests](https://github.com/kubernetes/kubernetes/issues/51540) added support for Windows
- [Conformance tests](https://github.com/kubernetes/kubernetes/pull/108592) added support for Windows

* Check if pathExists before performing Unmount ([#39311](https://github.com/kubernetes/kubernetes/pull/39311), [@rkouj](https://github.com/rkouj))
* Adding kubectl tests for federation ([#38844](https://github.com/kubernetes/kubernetes/pull/38844), [@nikhiljindal](https://github.com/nikhiljindal))
