How to restore Win7 mouse right click New Notepad function

My friend's Windows 7 mouse right click to select New has no notepad, let me help him find it back, in fact, very simple, just need to import a registry file.
Open Notepad first (or enter %SYSTEMROOT%notepad.exe in "Run" to open Notepad), then copy the blue code below and save it as a "notepad.reg” file. Then double-click to import into the registry, so that the notepad in the right mouse button is out.
When pasting, please use “\\” instead“/”
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT.txt]
@="txtfile"
"Content Type" ;="text/plain"
[HKEY_CLASSES_ROOT/.txt/ShellNew]

[HKEY_CLASSES_ROOT/txtfile/shell]
[HKEY_CLASSES_ROOT/txtfile/shell/open]
