I currently have Quicken Classic Deluxe, having used Quicken for decades. I use Quicken only for household cash management and checking account reconciliation. Microsoft is dropping support for Windows 10 and Windows 11 is not supported by Quicken. So what to do? To stay with Microsoft I will have to purchase a new computer with Windows 11 before October, 2025 [Edited - Corrected Year]. Because I will not be able to install Quicken, I'm thinking about using this old Windows 10. I just tested while completely offline for security and so far it is working for my needs. It put up a fight when I opened up but I just kept closing the nagging dialog until it stopped blocking me. I had no trouble creating a new offline cash account. What surprises me is that Quicken does not urge the potential new customer to check System Requirements. The section "Before you Buy" does not have a direct link to the System Requirements page!
