While enabling the Advanced Features option, you must make sure that you turn the feature off again as soon as you have removed the unwanted Active Directory object from the domain controller. Since the feature that provides protection against accidental deletion is object specific, you are required to disable the feature for each and every Active Directory object individually that you want to delete.
For example, if you want to remove OU-01 from the Active Directory domain controller, you must disable the protection on that particular OU. Likewise, if you want to remove OU-02, you must disable the protection on the second OU as well.
The protection against accidental deletion is not only enabled for Organizational Units, but for almost every Active Directory object.
Here’s how you can delete an OU (or any other Active Directory object) from the Windows Server 2012 Active Directory domain controller:
- Log on to the target Windows Server 2012 Active Directory domain controller with either Enterprise Admin or Domain Admin account.
- If not already started, initialize the Server Manager window from the bottom left corner of the screen.
- On the opened Server Manager window, go to Tools from the menu bar.
- From the displayed list, go to Active Directory Users and Computers.

- From the displayed list, click Advanced Features to enable the option.

- Once the Advanced Features are enabled, right-click the target OU that you want to delete.
- From the displayed context menu, go to Properties.

- On the opened object’s properties box, go to the Object tab.
- On the displayed interface, uncheck the Protect object from accidental deletion checkbox.

- Once done, click OK to save the modified settings.
- Right-click the OU, and from the context menu, click Delete.
- On the displayed confirmation box, click Yes to provide your consent to confirm the deletion process.
