What is KernelOS
KernelOS is a community-maintained Windows 11 build focused entirely on gaming performance: reduced input latency, trimmed background services, and scheduler tweaks designed to prioritize foreground game processes.
The 23H2 AIO release
This All-In-One ISO bundles the core KernelOS build so you can install straight from USB without extra steps. It's the version most creators (including this channel) recommend as the starting point.
Community support
KernelOS has an active Discord where updates, troubleshooting and new Playbook-style tweaks get shared regularly — worth joining if you plan on using the build long term or run into install issues.
Install walkthrough
Flash the ISO to a USB drive with Rufus, boot from it and follow the setup — the full step-by-step is in the video above, including a dedicated companion guide if you want extra detail on the install process.
Frequently asked questions
Is KernelOS free to download?
Yes, the AIO ISO is distributed free through the download link on this page and the creator's own channels.
What's the difference between the 23H2 and 25H2 KernelOS AIO?
The 25H2 AIO is the newer release, based on a more recent Windows 11 build with an updated post-install script and toolbox — 23H2 remains the most downloaded legacy version.
Is KernelOS good for low-end PCs too?
It's tuned primarily for gaming performance rather than raw minimum specs — pair it with at least 6-8GB RAM for the best experience.
