Use the Notepad feature in Windows to create a Desk Top Journal.

Click on Start, Run, then type "notepad" (without the quotes) and click on OK. In Notepad type ".LOG" (all caps, no quotes) as the first line of the text and press Enter two or three times. Save this Notepad file in your C:\Windows\Desktop folder using any filename you choose. Now, whenever you want to make a note, just double-click on the shortcut to this file on your Desktop, and Notepad will automatically add a time and date stamp.
