Windows operating systems use special permissions to control who has access to certain files and folders. In general, Windows assigns the permissions to a file based on its parent folder, so that the administrator doesn't have to assign permissions for each individual file. The file is said to "inherit" its permissions from the parent folder. Turning off permission inheritance, however allows any file or folder to have its own permissions setting, separate from the parent folder.
Click "Start" and select "Computer."

Navigate to the file or folder to which you want to set permissions. Right-click the file or folder and choose "Properties."
Click the "Security" tab and select "Advanced" to view the permissions options.
Click the box next to "Inherit from parent the permission entries that apply to the child objects" and click "OK" to save the settings. This will disable permission inheritance for the file or folder and its permissions settings can be modified separately from the parent folder.
If you do not see the “Security” tab in step 3, you will need to disable simple file sharing in the file explorer by clicking “Tools” and selecting “Folder Options.” Click the “View” tab and remove the check from the box next to “Use simple file sharing.” Then click “OK.”
