Key Name
Type
Description
(Default)
REG_SZ
Typically empty; presence confirms app has been launched
📝 Notes
All user preferences (recent files, language settings, themes, plugin config) are stored in %APPDATA%\Notepad++\ as XML files, not in the registry.
The 64-bit installer places keys under HKLM\SOFTWARE\Notepad++; 32-bit on a 64-bit Windows will use HKLM\SOFTWARE\WOW6432Node\Notepad++.
Shell context menu entries ("Edit with Notepad++") are registered under HKCU\Software\Classes\*\shell\Notepad++ (per-user) or HKLM\SOFTWARE\Classes\*\shell\Notepad++ (system-wide), depending on install options.
