To achieve the lowest possible latency, KernelOS disables or modifies many of Windows' built-in security features. According to its documentation, "KernelOS has the majority of Windows security mitigations disabled with the aim of improving performance". For example, the changelog for a version of KernelOS notes changes such as setting "No eXecute (NX) back to OptIn" and disabling the "Fault Tolerant Heap". This is a critical distinction for a standard user and a major potential security risk that should not be overlooked. Windows 10 October 2018 Update (version 1809) -
The Windows 10 NT kernel in Build 17763 features a lighter, more streamlined scheduling architecture compared to later versions. For example, the changelog for a version of
: Version 1809 features a leaner CPU scheduler compared to modern iterations like Windows 11 24H2 or 23H2. This ensures lower scheduling overhead on mid-to-high core processors.
: The underlying NT kernel allows for cleaner process scheduling without modern security virtualization features (like VBS/HVCI) degrading system frames per second (FPS).
Furthermore, in the realm of custom OS creation, the 1809 update of Windows 10 is a common starting point for 'debloating' and performance tuning. The creator of KernelOS has released multiple versions of the OS, including builds based on newer versions like 22H2. However, the 1809 edition is often highlighted by users as a reliable choice for achieving the best possible performance in games.
