regedit.exe is a GUI based registry editor. A console based registry editor is reg.exe

Surprisingly, at least to me, regedit.exe is located under %SystemRoot% rather than under %SystemRoot%\System32.

regedit.exe can be used in cmd.exe to import data into the registry or to export portions of the registry.

Showing an (independent) registry hive

The menu File -> Load Hive allows to show an «independent» registry hive. This menu is active when one of the «top level» keys (such as HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER) is selected.

This operation only shows the data of the hive, it does not import it.

When such a hive is loaded, its data can be modified normally.

The menu File -> Unload Hive will disassociate the loaded hive from regedit.

See also reg load and the WinAPI function RegLoadAppKey.

Favorites

The menu Favorites allows to add and remove registry paths so that they can quickly be navigated to. Added paths are also shown in this menu.

The favorite paths are stored in the registry under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Applets\Regedit\Favorites

Opening the registry at a given key

Unfortunately, regedit.exe does not have a command line option to specify a registry key that should be displayed when regedit.exe starts.

However, regedit.exe stores the last visited key in the registry (where else) under the value LastKey in the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Applets\Regedit.

So, in order to open the registry at a specific key, one needs to first change the value of LastKey and then start regedit.exe.

This idea is implemented in the batch file regat.bat and the PowerShell version regat.ps1. regat stands for registry at.

The same idea is formulated with the Perl module Win32::TieRegistry which can be used to manipulate the registry with Perl: op-reg-at.pl.

Another tool that does the same thing is regjump.exe (by Sysinternals).

Exporting a sub-tree

Choosing *.txt format when exporting a sub tree causes the produced file to reveal the time stamps of the last write time.
