Hello,

The issue is most likely caused by the change of the default GH Actions
Windows image. See https://github.com/actions/runner-images/issues/14017
You can try using `windows-2022` instead of the current `windows-latest`.
It should behave as before.

Alternatively, I have prepared a PR with a fix here:
https://github.com/apache/httpd/pull/659

Regards,
Vladimír Chlup
