The method turned out to be very simple
Modern consumer processors do not support very old versions of Windows. Fans of old computer games know this very well, who have to assemble a PC for retro gaming for their tasks. However, an enthusiast with the pseudonym O_Mores managed to run Windows NT 4.0 on the latest Intel CPU without using a virtual machine.
The author described his project on Reddit. Overall, the launch process was not that difficult. The author took an SSD with the Windows NT 4.0 operating system already installed on some old PCs. He then connected the drive to a modern Core i3-13100F-based PC.
27-year-old Windows NT 4.0 launched on a modern Intel processor without emulation
Of course, without additional manipulations, this method will not work. But to bypass it, you only needed to use the UniATA driver.
Judging by the video, the system worked perfectly, including being able to run games. Let us remember that Windows NT 4.0 was released back in 1996, that is, almost 30 years ago. At the same time, there were processors on the market such as the Pentium II with its single core, frequency up to 450 MHz, and 350 nm process technology.
