I just completed federal return with TT Home and business on a desktop still running windows 7. I will be upgrading to windows 10 in a few weeks but must first complete a critical project and in my case, upgrading to Win 10 will require a hard drive reformat. I would really rather not do that until this project is complete so my question is -- if I proceed with a state download to windows 7 so I can complete my state return, will I be able to download the state product again after upgrading to windows 10 without being charged or will I be charged if I download a second time, even though it will be for the same state and downloaded to the same computer?
