Our Favorite NT Registry Entries




Beware! Make sure you have a backup of the registry and are 100% confident of the syntax of the entries before you change anything. If you mess up, your NT system may never boot again, and you will have to reinstall NT. Try to tweak the registry indirectly whenever you can through control panel/services, system policy editor, and other such utilities.
