Linux kernel inside of WSL 2 will be serviced via Microsoft Update

According to the Microsoft Windows blog, in the Windows 10 Insider Preview Build 19645, Microsoft has adjusted the Linux kernel service model in Windows Subsystem for Linux 2 (WSL2). In Windows 10 Version 2004 and earlier versions, the Linux kernel of the subsystem is pre-installed in the Windows image, but from the latest beta version, Microsoft removed the Linux kernel from the Windows system image.

The reason for deleting the Linux kernel is because there is no need to pre-install it because the Linux kernel and peripheral software will be provided through Windows Update from the new version, which means that Microsoft can push the new version of the kernel to users at any time through Microsoft Update. Of course, it is not just the Linux kernel. Peripheral software including third-party software such as drivers, touch panel drivers, etc. will also be provided through Windows Update. The advantage of this is that users can always get the latest kernel and drivers to ensure that the Linux subsystem can run stably.
