Here is the documentation of the relevant user option:

   w32-use-visible-system-caret's value is nil

   Flag to make the system caret visible.
   When this is non-nil, Emacs will indicate the position of point by
   using the system caret instead of drawing its own cursor.  Some screen
   reader software does not track the system cursor properly when it is
   invisible, and gets confused by Emacs drawing its own cursor, so this
   variable is initialized to t when Emacs detects that screen reader
   software is running as it starts up.

   When this variable is set, other variables affecting the appearance of
   the cursor have no effect.

   Defined in `C source code'.
