  "abstract": "We study the topological non-Abelian string and its classical stability in models with two Higgs fields to achieve the symmetry breaking of ${\\rm SU}(N) \\otimes {\\rm U}(1)_X\\to {\\rm SU}(N-1) \\otimes {\\rm U}(1)_{X^\\prime}$. The topological origin is due to the global $\\widetilde {\\rm U}(1)$ symmetry and its breaking in the scalar potential. The most generic winding configurations of arbitrary integers of $(n_1\\,, n_2)$ are considered. The stability of the topological string is analyzed based on the time-dependent perturbations to the string background and numerical solutions to the coupled Helmholtz equations of the perturbed Fourier modes. We present the constraints on the stable regions for the $(n_1\\,, 0)$ configuration (or equivalently the $(0\\,, n_2)$ configuration). For the general winding configurations of $(n_1\\neq 0\\,, n_2\\neq 0)$, we point out the stable regions only exist in the semilocal limit of the large mixing angle of $\\vartheta_N\\to \\fracπ{2}$.",
