If you are the kind of user that plays around with the Windows Registry far too often and find the default regedit.exe tool cumbersome to use, there is a shell extension that integrates Windows Registry with Windows Explorer that allows you to browse and edit the Registry like they are folders and files.
The Windows Registry shell extension loads the entire Registry hive into My Computer as a virtual folder.
In the Registry folder you can browse and edit values of the registry under the HKEY_CURRENT_USER branch (or HKEY_LOCAL_MACHINE if you launch Explorer under the Administrator account). You can also create new keys and values just like the RegEdit tool, and delete existing ones. Be warned that although it makes Registry editing easier, it also makes it awfully easy to screw up your system. One slip, and Windows might refuse to load or software stop working.
I feel it’s better, that you not install this shell extension unless you really need to.
