I'm far from a computer expert, other than games I don't know much at all. I was trying to get a file for a game to work so I turned to google for help, It looks like I've gone onto something I shouldn't have. The instruction on the website was to click start and type "Shell32.dll" into the search box. The next instruction was to open it with Notepad, which I did... The box saying something like "always open using this program" was ticked. After spending time googling what I'd just done it seems like that was a huge mistake, I have no idea how to change it back to its original state. So far everything seems to be fine but from what I read on another site the shell32.dll file has something to do with the start up so I haven't turned my laptop off yet.
