Just a quick note to let you know that Quickbooks is NOT CURRENTLY SUPPORTING its product on Windows 10. This means that if you upgrade your operating system and your Quickbooks stops working, you are going to be out of luck until Intuit finishes their testing and irons out the glitches. I am speaking from experience, as I have spent numerous hours on tech support today with no resolution in sight.
I strongly encourage you to WAIT. Don’t upgrade until Quickbooks adds Windows 10 to it’s list of supported operating systems. When this happens, it should be listed on the Quickbooks Support page.
Best of luck!!
