Uses of 'Regedit' Command in Windows® 7
What are the consequences of editing the registry?
The registry is the central location for all the system settings, hardware, Operating Systems, and software. It is designed to replace DOS configuration files, Win 3.xx settings, and the .inf section. It is the best and also the most dangerous place to change the behavior of your operating system. Any change in the registry affects the entire system. The tool for editing the registry comes with Windows itself. The 'regedit.exe' is found in your 'Windows/winnt' folder which creates a shortcut in your quicklaunch bar, applauncher, or whatever. It helps to display the folder structure of the registry and allows you to easily add, edit, and delete keys and values. The main drawback is that it does not ask for confirmation. So, it is very easy to corrupt the registry. The Regedit enables you to export and import registry keys/values. You could just select a key in the left pane; choose 'Registry' in the toolbar and then Export. With 'Registry editor', the user could locate a key or value, add a subkey, change a value, delete a value, and rename a value.

Tips to edit the registry
In order to edit the registry, go to 'Start' and then click 'Run'. Now type REGEDIT and click 'OK'. The Registry Editor window would open. You could browse to the key containing the value that you wish to modify. Then click once to highlight the key. The values contained in the key would appear in the right pane. You could right-click the value which you want to modify. The right-click menu provides options like Modify, Modify Binary Data, Delete, or Rename.
Before editing the Registry or opening the Registry Editor, the user should back up the Registry. The mistakes in the Registry Editor cause big problems in Windows. Even if you don't plan to edit or manipulate the Registry, it is still important to take a backup. It's just as important to check those backups and make sure they work properly.
The change in the registry setting would affect the complete system. Whenever you install or uninstall software, it is automatically stored in the registry. So, if the user unknowingly changes the values in the registry, the particular software or hardware would not be accessible. It would cause errors in the system and the performance of the system would deteriorate.
