Make sure you understand how to undo the changes these tools make in the inevitability that you break something you want to reenable later on.

The best way to manage privacy settings is to learn Group Policy as this is the method officially created for Enterprise admins that need control over these settings. Some of these tools simply apply Group Policy settings and are easily reversed, others apply registry hacks or even delete system files and can royally f*ck your install. Do your research. You've been warned.
