Take that document and file it somewhere in C: not to be moved.
Go to your desktop and right click, choose ‘New’>‘Shortcut’,
In the dialog type explorer then a space, then go to that file, press and hold ‘Shift’ then right click on the file and choose ‘Copy as path’, then paste that into the shortcut creation dialog and press ‘Next’; name it whatever you wish and click finish.
File explorer icon will be the default but you can change it by right clicking on the shortcut, choose ‘Properties’>‘Change icon’. (You may have to round up an appropriate icon from the internet and store it in a place not to be moved, (remember it has to be an .ico type (icon file).
Then you can drag that to the taskbar and delete the desktop shortcut if you wish.
I found this on tenforums great site.
