Windows Registry Editor (regedit)

Contributor(s): Eddie Lockhart

The Windows Registry Editor (regedit) is a graphical tool in the Windows operating system (OS) that allows authorized users to view the Windows registry and make changes.

Only advanced users should work with the Windows Registry Editor and administrators should always create a backup of the registry before making changes because, unfortunately, if a change is made incorrectly, the computer’s operating system may cease to function. Fortunately, the Windows Registry rarely needs edits, but situations do arise in which administrators must make adjustments to the registry in order to import/export .REG files or create, delete or make changes to corrupt registry keys and subkeys.
