I may be in the wrong catagory but I could not find the right one for my question and it is on a windows 7 computer. I am in a computer class which starts in less than an hour. My teachers aide broke my compter and I am suppose to fix it. I am an advanced student but I can not figure out hom to fix what he did. When you click on a .TXT file a regedit direcory box opens. I have researched and researched and found no answers to this. Someone please help. He said its something you type in the cmd box.
