Get your taxes done using TurboTax

The in-place upgrade of my Windows 10 IoT Enterprise LTSC 2021 virtual machine to Windows 11 IoT Enterprise LTSC 2024 was successful, with no issues noted (except that Windows 11 is a pig :@)

It turns out that this virtual machine did not have a virtual TPM chip enabled in the virtual hardware.  But TurboTax for TY2025  installed just fine, and activated without a hitch.  So there should be no need for a TPM chip on a physical PC -- at least as far as TurboTax 2025 is concerned.

See screenshot below after TurboTax was activated (this is Home & Business edition).  Again, it's obvious they really want to move us off the Desktop product ASAP.

Also @VolvoGirl this answers your question as to whether or not migration to the Online product requires any further payment.  Apparently that's not required (for now at least).  However, per the dialog "TurboTax Online is available starting December 17, 2025".  Also note all this extra fine print:

*Includes one federal and state return. Additional fees apply for more returns, upgrades, and add-ons. File by April 16, 2026.  $10 Retail Club credit and TurboTax Advantage benefits such as Audit Defense, do not transfer to TurboTax Online.
