@user17598960542 If your Windows OS becomes compromised in some way (etc. malware, viruses), then any software or data can be viewed, stolen, deleted or taken hostage - TurboTax Desktop, your spreadsheets, your web browser, etc. Regardless of whether you have TPM or not, Microsoft is no longer providing software updates, security fixes, or technical assistance to Windows 10 PCs, which will make it harder to keep your computer secure. Which is why TurboTax Desktop 2025 will not be made to work on Windows 10.
