Content compression spontaneously turns on in Windows 10. How to turn it off?

Question

Windows

In windows 10, two blue arrows began to appear on the icons indicating compression. After disabling this function through the File Properties, after some time, compression reappears on the same files and folders. How to fix it?

Answer 1

Under admin in powershell command line
compact /compactos:never

Answer 2

"Spontaneously" this happens when there is not enough space on the system partition. Free up some space.
