- Starting Regedit
By default, Regedit.exe is copied to the %SystemRoot% (for example, D:\WINNT)
during the installation of the operating system. To start Regedit.exe, find the file and
double-click it, or use the Run command from the Start menu.
Like most of the other viewing tools now available for Windows operating systems,
Registry Editor has a user interface similar to that of Windows Explorer. Note that
Regedit is simply a tool for registry visualization, and all of the magic is hidden behind
the scenes rather than in the UI.
In practice, the similarity between Regedit and Explorer goes further than simple
analogy. For example, the same menu commands for keyboard shortcuts are used for
creating new registry elements. Regedit.exe uses context (right-click) menus similar to
Explorer. Despite interface improvements, however, Regedit.exe doesn't provide any
warnings to the user, nor does it recognize errors. What's more, it doesn't have an Undo
command, meaning that most operations are irreversible.
