I am running Windows 7 on my computer. The problem with my computer is that all of my desktop icons have been converted into .lnk file. I don't know how it happened and I even do not know how to solve this problem. I have tried fiddling around the properties but didn't find anything solid that could fix the problem. If I try to click on these files to see what it is all about, I get the Media Player opening the file and it says the file type is unknown and so could not open this file. What is going on in my computer and is there any way to solve this problem?
