I don't plan on "hacking Turbo to run on Win 10". Nor do I plan to "hack" Windows 10 to make it look like Windows 11. I just want to have a look at what TurboTax is doing to determine that it's running under Windows 11. It might be so foolishly simple that a workaround could hardly be called a hack. Again, Intuit will likely take the cheapest route possible to "enforce" their requirement for Windows 11, which is usually the easiest to implement (and workaround).
Also, I seriously doubt that Intuit will spend any money to add any functionality to their desktop product that requires features which are exclusive to Windows 11. So there shouldn't be "any issues during your tax process with updates, forms, e-filing etc"
You are correct though that Intuit can simply refuse customer service if a support log shows anything that indicates that TurboTax is not actually running under Windows 11. In that event we could do an in-place upgrade to Windows 11 if that's what it takes to get support from Intuit. But as several others have pointed out here, in many cases that can be done without having to resort to purchasing a new PC.
In any case I simply won't let myself be driven by Intuit or Microsoft to spend money for a new PC when there's absolutely nothing wrong from a security standpoint with my current hardware. I'll migrate to Linux and do my taxes on PDF forms if that's the only way to get out from under their corporate enforced "rules".
