I use Unlocker and UltraEdit. Each of them attaches itself to the context menu for all items in Explorer. UltraEdit uses HKEY_CLASSES_ROOT*\Shell\Ultraedit\Command to do so. Unlocker dynamically adds its entry from its DLL file.
My fingers are used to right-click followed by U to start UltraEdit. Unlocker adds itself with U as a hot-key in the menu. Here’s how to change it.
- Using UltraEdit, open C:\Program Files\Unlocker\UnlockerCOM.dll
- Search for "&unlock".
- I replaced the & with _
- When I tried to save the file, it was write-locked.
- I killed Explorer.exe and Unlocker*.exe via Task Manager.
- Then I saved the file.
- Then I re-started Explorer.
