You cannot directly download an older kernel. But you can use the Windows Update Catalog (catalog.update.microsoft.com) to search for a specific KB update that includes that kernel version. Then manually install that update package.
No. The Windows kernel is proprietary, closed-source, and only distributed as part of the Windows OS or its updates.
To summarize:
Your system’s stability and security depend on treating the kernel as what it is: the protected, signed, and integrated heart of your OS, not a standalone download.
Final action step: Bookmark the official Microsoft Windows 10 download page (https://www.microsoft.com/software-download/windows10) and ignore any other result promising a “kernel download.” kernel os windows 10 download

Step-by-step download:
Where is the kernel inside the ISO?
After mounting the ISO, look in \sources\install.wim – inside that image, the kernel resides at \Windows\System32\ntoskrnl.exe.
Avoid them. Modified Windows kernels (e.g., "ggOS kernel," "ReviOS kernel") violate Microsoft’s license, disable security features (like PatchGuard), and can lead to permanent system compromise.
