Both are recognized on Windows so that's not really an issue to mix them.

It would be good to get more information, or it will be difficult to
diagnose a problem, something that got fixed lately for pg_upgrade on
Windows is for example the detection of copy failures:

Previously, file copy failures were ignored on Windows due to an
incorrect return value check.
