The only caveat while configuring settings visibility on Control Panel is that you need to know the exact name of each item you want to hide from users beforehand.
Microsoft Windows XP Control Panel Windows XP introduced two different ways to display the Control Panel: Classic View and Category View.
By default, Windows displays the Control Panel in Category View (shown above), listing icons under broad categories rather than each one individually.
You could restrict total access to both, Control Panel and Settings, but if that isn't an ideal solution, on Windows 10, it's possible to use the Local Group Policy Editor and the Registry to hide only those settings you don't want users to change.
You can also restrict access to pages in the Settings app, but to do that, you need to follow these instructions instead.
