There is a workaround in PR pytorch/pytorch#190360. Hi @atalman why we don't upgrade the SDK version directly? |

Works for pytorch/pytorch#184352 to support PyTorch Windows build with python 3.15.
In PR pytorch/pytorch#186033, we plan to enable python 3.15 PyTorch build, but missing numpy pre-built packages, so we need source code build numpy before the PyTorch build. But numpy build on Windows requires Windows SDK version > 22000 to include the missing header file
stdalign.h. Refer https://github.com/pytorch/pytorch/actions/runs/29386139923/job/87259785893?pr=186033#step:11:2463
