Why are my .txt files printed when I double-click them?

"Open up a folder and then go to the menu:

Tools > Folder Options > File Types

Go down to the TXT extension and then click the Advanced button for the Edit File Type dialog:

If you are missing the open action

To create a new open action, take the following steps:

Click New. A New Action dialog will pop up
For Action, enter open
For Application used to perform action, enter
""C:\WINDOWS\system32\NOTEPAD.EXE %1""
Click OK

(Adjust the program file path as necessary if you prefer opening with another text editor.)

In the Edit File Type dialog:

Select open under the Actions list
Click Set Default
Click OK
Close out the Folder Options

This should now set back the default action of double-clicking on a .txt to open instead of printing."
