LKBEN10634: Howto delete a registry key by using a reg file

Symptom

Cause

None

Solution

To import a key into the registry you can click on a reg file and import it. The same regfile, with minimal changes, can be used to delete this key form the registry again.

In the following example you see the content of two registry files. The first one will add a "Send To" context menu and the second one will delete this again. Please note that having "Send To" in your context menu is the default under Windows.

Please also note the minimal difference between the two. In the second on there is a minus before the registry key! (this - sign has to be beween the brackets)

First regfile:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AllFilesystemObjects\shellex\ContextMenuHandlers\Send To]
@="{7BA4C740-9E81-11CF-99D3-00AA004AE837}"

Second regfile:

Windows Registry Editor Version 5.00

[-HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AllFilesystemObjects\shellex\ContextMenuHandlers\Send To]
@="{7BA4C740-9E81-11CF-99D3-00AA004AE837}"
