When I right click on a batch file, the Edit option that opens it in Notepad is not there. How do I get it back?
If that file is marked as read-only, then that'd make sense for that to be missing.
Right-click the file and select "Properties". Make sure it's not marked as "Read-Only". I guess that "Archive" property may also cause this, not sure what that really does, actually.
If that's not it, you could always try opening the file directly from Notepad. Start > Run > notepad. Then open that file, edit it, save it. You may have better luck yet, if you make a copy of the file first.
Edit: Here's how to manually add the edit option
