The kernel version *is* provided by Microsoft - it has been engineered by them to work with Windows. Having just updated a Windows 10 laptop - there was a wsl.exe update to install. The WSL version I had installed was from the Microsoft store as version 1.0 After the latest update today 20230307: wsl.exe --version reports WSL version: 1.1.3.0 Kernel version: 5.15.90.1 WSLg version: 1.0.49 MSRDC version: 1.2.3770 Direct3D version: 1.608.2-61064218 DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp Windows version: 10.0.19045.2546 Essentially, as you do your updates so updated kernels get posted as part of Windows Update from Microsoft. Hope this helps, Andy Cater
