Install packages required to build the kernel:

• Ubuntu: install-deps-ubuntu.sh
• Other distributions are currently not supported

Start from your running configuration: $ zcat /proc/config.gz >running.config

(Optional) Make sure to have ebpf enabled: $ assert-config.sh running.config

Build the kernel: $ make KCONFIG_CONFIG=running.config bzImage $ make KCONFIG_CONFIG=running.config modules

Install the kernel: $ copy arch/x86_64/boot/bzImage to “/mnt/c/$(wslvar -s HOMEPATH | tr ‘\’ ‘/’)/” $ make KCONFIG_CONFIG=running.config modules_install

Configure new kernel in %UserProfile%/.wslconfig (https://learn.microsoft.com/en-us/windows/wsl/wsl-config#wslconfig): kernel=c://users/USERNAME//bzImage

If the new kernel fails to load, remove the kernel from the config file and restart WSL.
