Search for Ubuntu in the Microsoft Store (I only tested this system. If someone likes to toss, they can also try other systems, such as SUSE and Debian). The process of installing Ubuntu in the application page is very simple, just like installing software.

Search for Ubuntu in Cortana in the lower left corner, and click to enter. The interface you see is just like our terminal interface in Ubuntu. Test the LS command in this window, and it is correct.

Xrdp should be started in the terminal before each remote connection, and the window cannot be closed.
