In this forum I have seen that some users install Linux on a new SSD, saving the Windows SSD for future use. Thus, recovering the initial state of the computer is as easy as installing the original SSD. I don’t think it’s a bad idea, given the prices that SSDs have today.
On CHUWI and other computers, with Windows 10 installed and running, I have used the Recovery function to reinstall Windows removing everything, which leaves the computer ready for initial setup.
On non CHUWI computers, I have made clean installs of Windows, after taking note of the product key code.
