The Registry Editor in Windows isn’t the most user-friend tool. Navigating to keys is pretty cumbersome. However, there are third-party tools that help—a godsend if you do any registry edits.
Windows Sysinternals offers a command-line tool, called RegJump. It accepts registry paths in standard form (e.g. HKEY_LOCAL_MACHINE) or abbreviated form (e.g. HKLM) and opens Regedit to that path. Then you can also add a shortcut to the right-click menu in Internet Explorer with the Go to Registry Key tool. Then you can simply highlight a path in IE, right-click it, and select Go to Registry Key.
Another tool you might try is JumpReg. It offers numerous shortcuts and tools for Registry navigating and editing. You open keys from paths you’ve copied to the Clipboard, bookmark keys, create desktop shortcuts to keys, jump between same keys in Current_User and Local_Machine, and more.
