Though we recommend using Windows 11, the Canadian version of TurboTax Desktop 2025 will run on Windows 10. Please see this TurboTax Canada FAQ for more information: How does the end of support for Windows 10 affect my TurboTax Desktop experience? 

Thank you for your help. That was a very fast response!

I have installed Turbotax on my 2010 desktop and have had no issues with it.  

@Delphision Glad to hear that!
