Open with Notepad context menu

Manual Registry Hack

Open regedit.exe through the start menu search or run box, and then browse down to the following key:

  HKEY_CLASSES_ROOT\*\shell

Right-click on “shell” and choose to create a new key, calling it “Open with Notepad”. Create a new key below that one called “command”. Double-click on the (Default) value in the right-hand pane and enter in the following:

  notepad.exe %1

The change should take effect immediately… just right-click on any file and you'll see the next menu entry.
