You try to enable TPM on virtual machine, but once you start it up you encounter the error: 'Virtual Machine' failed to start worker process: The computed authentication tag did not match the input authentication tag (0xC000A002). 

As far as I can tell, when the TPM is activated on the virtual machine, the keys aren't properly created the first time. The only fix for this is by deleting the VM, keep your VHDX files of course and recreate it and configure it as it was before. In my case I don't have many settings configured just things like auto-start so recreating it wasn't an issue and it solved the problem with the error.
