+For the Windows Explorer right click context menu.
+Use the HKCR (`HKEY_CLASSES_ROOT`) path for administrator, 
+and HKCU (`HKEY_CURRENT_USER`) for only the current user.
+
+**Background of right panel**
+```
+HKCR\Directory\Background\shell
+HKCU\Software\Classes\directory\Background\shell
+```
+**Directory icon**
+```
+HKCR\Directory\shell
+HKCU\Software\Classes\directory\shell
+```
+**File**
+```
+HKCR\*\shell
+HKCU\Software\Classes\*\shell 
+```
+
+### How to add a command (sample install script):
+
+If prompted, do not override keys unless it's for the command/knowledgable.
+```powershell
+$name = "Open with Sublime"
+$cmd = """C:\Program Files\Sublime Text\subl.exe '%1'"""
+
+reg add HKCU\Software\Classes\Directory\Background\shell
+reg add "HKCU\Software\Classes\Directory\Background\shell\$name"
+reg add "HKCU\Software\Classes\Directory\Background\shell\$name" /d $cmd
+```
+<small>If manually adding via regedit, note that these are keys (not string values)</small>
+
+
+`%1` indicates the current file. [more args]({{ site.baseurl }}{% link _notes/assoc-filetype.md %})
+
+Other paths to try:
+```
+HKEY_CLASSES_ROOT\AllFileSystemObjects\ShellEx\ContextMenuHandlers
+HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\
+HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers\
+```
+
