I have a Gateway NE71B laptop running Windows 8.1. I created a shortcut to a text file located in a folder in Documents. I moved the shortcut to a folder on Desktop. I have been using the shortcut for some time now. Today, when I tried to open the text file using the shortcut, I got a prompt asking for my network credentials. I tried my computer log on pw, my Microsoft pw for downloading apps, and my Wireless Network Key. I don't remember ever setting up any other password for computer access. This has never happened with any other file or shortcut. I was able to delete the shortcut and create another one that doesn't prompt for network credentials. I am not networked with any other computer. How can I keep this from happening again or at least find out what password it was asking for.
