My system says it can't find misconfig

[Robbo54]

Using Firefox and Windows 7. IE and Chrome available. Tried Skype, screeching deafening feedback. Hung up. Screen went blank - pale blue with black rectangle top right. Then black screen and a big bad white message about a dreadful near-Blue Screen error. It vanished before I could read it. Message came to check Windows Security. Found link in Action Centre - said protection wasn't on. I'm a security freak - it should be on. Shut down, opened up in Safe Mode. Tried to start Windows Security - said it couldn't find it. Read somewhere that it wouldn't work in Safe Mode. Thought about Restore point but listed date was 2 weeks ago, would lose too many programs. Shut all down again. Started up ok but everything looks different, basic fonts, simple, 2D. MS Word icons pixelated. Looks like I'm still in Safe Mode. Thread here says reboot to get out of Safe Mode by typing misconfig in Windows button+R. Did that - it said it can't find misconfig. Where do we go from here?

The program is "msconfig" -- no "i" ...
