- Improved the error message shown when a Pod using user namespaces was created on a runtime that did not support user namespaces. ([#131623](https://github.com/kubernetes/kubernetes/pull/131623), [@rata](https://github.com/rata))

- Compatibility testing with Windows Server 2016/2019/2022

### Test Infrastructure Requirements
- Windows Server test environment with:
  - Failover clustering
  - RDMA-capable network adapters
  - DFS namespace
  - Multiple network interfaces
