If by "the text" you mean the text copied the second time from another
application, then Emacs on MS-Windows behaves the same as on X in this
scenario.

So now the only issue left (for me) is that I don't think I understand
why the OP doesn't like this: after all, the original text from the
clipboard is still available in the kill ring, and can be pasted given
enough M-y, or using the Edit menu-bar menu, or using the new feature
of M-y when it is invoked not after C-y or another M-y.
