How to quickly enable OS X Finder's Simple Finder mode

For those of you enjoying my ‘how to disable’ series, here’s another handy tip.
The built-in Parental Controls in OS X has a very useful option called ‘Use Simple Finder’ as shown below:
How to quickly enable OS X Finder's Simple Finder mode
Like most user interface features, there is a preference somewhere that toggles this feature on and off. Therefore instead of configuring Parental Controls, you can just simply enable the ‘Simple Finder’.
To enable ‘Simple Finder mode’, all you need to do is log in as an admin user and enter one line of command in the Terminal application (located in /Applications/Utilities/) as shown below:

defaults write InterfaceLevel simple;killall Finder

You will now notice that the Finder has restricted your access with less pull down menu options and a restricted Dock:

restrict access on osx via finder

To temporarily gain full access to the Finder whilst logged in, click the ‘Finder’ menu and select ‘Run Full Finder’, then type in your admin password to start the Finder in normal mode.
If you do want to revert completely back to the default setting, just enter the following command:

defaults write InterfaceLevel standard;killall Finder
