Thank you for
reaching out on the community and telling us about your issue. When it comes to the Quicken subscription both Mac and Windows are included within the subscription. You're free to use whichever product you'd like at the time. As it goes for converting the article down below will give us instructions on how to convert from Mac to Windows as well.https://www.quicken.com/support/converting-your-data-quicken-mac
It'll be under the header Windows conversion > Convert from Quicken for Mac to Quicken for Windows
With this you should be able to convert over to Windows before and try it out before you renew as well. If you do have any other questions please let us know.
