Windows 29.1 error - xargs MIA

[JF]

Using GNU Emacs 29.1 (newly installed) on Windows 10 Pro

Trying dired mode for the first time and marked several files, then hit "Q" for regexp query search and replace. I specify the search and replace strings, hit Enter, and it says "Searching ..." and then:

xref-matches-in-files: Search failed with status 1: 'xargs' is not recognized as an internal or external command,

from which I infer there's a path to some xargs analog that's part of the install but it can't find???

Thanks,

John.
