Keys create the paths to the various registry entries. For example, HKEY_LOCAL_MACHINE is a 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 HKEY_LOCAL_MACHINE is displayed, you need to use the Key registry entry to create the path for where the other registry entries 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.
Select a condition for making the registry change:
Create
Delete
To apply the setting to all subordinate keys, click Apply To All.
