I cannot reproduce this.  The cursor blinks for me on MS-Windows as
expected.

Some questions:

  . does the problem happen if you invoke "emacs -Q"?
  . are you invoking the GUI version of Emacs or the text-terminal
    version (by using the -nw command-line switch)?
  . what kind of "line cursor" do you see? is it a vertical line or a
    horizontal line? what is the value of the cursor-type variable?
  . do you have w32-use-visible-system-caret customized to a non-nil
    value?

By default, Emacs's cursor only blinks 10 times and then stops; it
resumes blinking after some input event.  Are you sure what you see is
not this behavior?

Thanks.
