This is the registry fix for computers in which the .txt or TXT file association has been removed. The end result is when you attempt to open a Text Document or .txt file, the Open With Dialog box will appear and you will not be able to open these files using windows. TXT Files Will Not Load You could go into your Windows Registry and edit it, which I highly discourage. You can download the file below and extract the file, and double click on the .reg (registry) file. You will get an “Are you sure dialog box”. Click yes and this should fix your problem.
