When dealing with networks, only approved administrators should have that key. But, most importantly, this access key should not rest in the users' hands. While it still may be appropriate to allow users to install certain versions of software to meet their individual needs, they should continue doing so by employing Wizards and property sheets which decrypt the Registry, but maintain the Registry's basic core intact.
Many property sheets display too much Registry information. Therefore, even a system administrator can tell you what each entry on a property sheet means.
