Messed up with MSConfig Settings... Need help...

Hello there,

I would like some help with a little issue. So, today I went on MSConfig and messed up with some stuff. On the "Start-up" bar as I remember I clicked on an option to load only basic programs or drivers or whatever it was and I cliked apply. I resterted my PC and after I restarted the only thing I could see was my background image and four icons on bottom right corner! It was the language selection but I couldn't use my keyboard at all. Nothing was working. There was the Internet icon but I didn't have Internet Connection another icon with some settings about some useless stuff and then the shut-down, restart or sleep button. I tried to boot my PC on Safe Mode but it didn't work. I can't press any on the keyboard! What am I supposed to do? I can't even right click! Please, I would like some help ASAP!
