Using Windows Update to keep your system up-to-date

Windows Update is a Microsoft service that scans your system to identify, download, and install updates for Windows and other components required by TurboTax, such as the .NET Framework and Windows Installer.

Using Windows Update helps ensure that your system is up-to-date with the latest security and performance enhancements. It's also a recommended troubleshooting step if you're having problems installing TurboTax for Windows.
