Windows 7 - Command Prompt Won't Open

I was messing around with the command prompt, trying to make a script to scare the shit out of my friend when he opens it. I entered the following code, under the assumption that it would make the prompt go full screen.

[Default.AddReg]
0x4,"Console","FullScreen", 0x1

After I hit enter it asked me if I wanted to overwrite FullScreen. I said yes and nothing happened to the prompt. But after I closed the window I was unable to open another prompt up. Task manager says its running, it just won't display it. I have tried restarting. Is there anything other than a reinstall that will fix this?

Where did you enter this code? In the registry?

In the command line (not sure if thats the registry).

Can you do a system restore to a few days before you made that change?

No I haven't set it up yet since my hard drive crashed. Thanks for reminding me though.

Mmm...the best I can suggest is for you to visit this thread, to see whether you think any of the posts in there might help you:

Where did you find this code that you enetred? Search the same source to see if there is a code to reverse it.
