If you are interested in experimenting with the Windows 8.1 Extended Kernel or Second System, these community resources are invaluable: Windows 8.1 Extended Kernel

An extended Windows 8.1 kernel can deliver necessary long-term support and functionality for constrained or specialized deployments, but it increases maintenance burden, security risk, and compatibility challenges.

Before installing any extended kernel components, apply the recommended prerequisite updates found on the win32 website. Failure to do so may render your system inoperable. "The procedure entry point could not be located

If you have an old netbook, a legacy industrial PC, or simply despise the telemetry-heavy architecture of modern Windows, the Extended Kernel is arguably the most exciting development in the "abandonware" space since the Windows XP unofficial service packs.
