Are there any better/newer ways to create a hidden operating system (Windows 10) than the one proposed by Veracrypt [0]?

I'm playing around with Plausible Deniability and the idea of having a hidden OS, where depending on the boot password a different OS (decoy or hidden) is booted. Usually these kinds of stuff are connected with illegal activities, but from a privacy point of view they offer a good technological challenge, especially nowadays :-)

I would assume that with the ongoing advances in encryption and/or whistleblowing, there would be easier ways to create a "secure" PC in case you wanted to be out of reach of different agencies.

I've seen that there are a few problems [1] with Windows updates corrupting the Veracrypt hidden/encrypted partitions.
