@user17613192960 just got another e-mail from TT about mid-October. It seems Turbotax is not giving in on the W11 requirement., There are possible workarounds, but no one knows which will work and which won't. They'll be more once Turbotax release 2025 and users with noncompliant computers see what works. They will probably post the info in this forum. The workarounds may invalidate the accuracy guarantee and if you need help from support that might not be provided,
I don't think anyone is sure if 2025 will or won't install on W10. this only applies to desktop users since online users can continue to use w10.
1) your options if you use desktop - switch to a competitor's desktop or some online app. It's likely this is a temporary solution since more and more apps are likely to require W11 in the future. (Just think of what MAC users go through every few years when their MAC OS is upgraded but Turbotax won't run on that version)
2) create virtual machine which requires an app to modify the Windows 11 registry before installation, so it thinks you have TPM 2.0, secure boot enabled and a more current cpu.
the VM allows both w10 and w11 to operate side by side but your computer bios must have the ability to enable Intel virtual technology. what that does is allows you to specify on a multicore CPU sores for w10 and cores for w11. also required is a memory allocation
