Keys create the paths to the various registry entries. For example, HKEY_LOCAL_MACHINE is a registry key at the root level, and HARDWARE is a key directly under it. The keys are displayed with folder icons in tree fashion. You can click the plus or minus signs to expand or compress the tree structure.
In the box where the HKEY_LOCAL_MACHINE key is displayed, you need to use the Key registry entry to create the path to where the registry changes will be placed.
To configure a Key entry:
In the box displaying your key tree, click the location where you want the key entered.
Click Key from the drop-down box > click Add.
New Key #1 is displayed.
Change the default key name to the key name that you need.
IMPORTANT: After typing the new key name, you must press Enter to save the change.
Select a condition for making the registry change:
Create
Delete
To apply the setting to all subordinate keys, click Apply To All.
