This should not be happening.  On windows pg_upgrade uses
CreateHardLinkA()
(https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-createhardlinka?redirectedfrom=MSDN)
if -k / --link option is used. The page mentions that only ntfs
filesystem is supported, is this what you're using?  Can you show the
full output of pg_upgrade in verbose mode?
