On October 14, 2025, Microsoft stopped providing updates, technical support, and security fixes for Windows 10. While they are offering a paid extended security updates (ESU) program for one year (for consumers), it will only cover critical and important updates (more info). Moreover, our analysis suggests that very few consumers plan to pay for the ESU program. Given that, we’ve made the decision to discontinue support for TurboTax Desktop personal software on Windows 10.
