As a techie it is often useful to quickly look at a file in notepad, so I always add it as a shortcut in the 'Send to' right click option of Windows explorer. Trouble is I always forget where to add the shortcut when I use a new PC! So for future reference...
1. In windows explorer go to the folder:
2. Right-click and select New->Shortcut
3. Choose file: %WINDIR%\notepad.exe
Obviously you can add other shortcuts in here too.
