Windows is preparing your devices.
Windows 10 1809 was the final version to fully support without mandatory enforcement of SHA-2. For industries running expensive legacy hardware (CNC machines, MRI scanners, airport baggage scanners), upgrading the kernel means replacing the hardware. 1809 allows these kernel drivers to load in Test Mode or with specific exemptions that later kernels (1903+) removed.
Microsoft released two major LTSC versions: 2016 (based on 1607) and 2019 (based on 1809). LTSC 2019/1809 is the preferred build for kernel-exclusive work because: kernel os windows 10 1809 exclusive

Below are three post options tailored for different audiences:
Contrary to intuition, for kernel-exclusive drivers, you set the system to optimize for "Background Services" in System Properties > Advanced. This tells the scheduler to prioritize driver threads over foreground UI threads. 1809 allows these kernel drivers to load in
Despite being out of support (mainstream support ended May 2020, extended support ended May 2023), a small but dedicated group of users maintains (Long-Term Servicing Channel). The LTSC variant uses the exact same kernel 17763, but without feature updates.
