Inside builder incompability with games anticheat sofwares

I want to change canary dev version to more stable version of windows. I even don't know how I got enrolled in the build insider but now I cannot even change the version since selecting other versions are off and cannot be chosen. I reinstalled my windows but still the same version installs whereas I deleted all of my data and fully reinstalled the windows. please let  me know how I can get rid of inside builder program and its unwanted updates.
