Huh!This is a strange warning. I bet!When I log in to my Windows 7 (build 7100), I'm getting a warning that I'm using an illegal version of Win7.http://img207.imageshack.us/img207/2858/win7genuine.jpgBut, when I take Computer -> Properties, I can see the genuine logo from Microsoft.As far as I know, win7 (build 7100) has free-license to use till mid-2010.Is this a serious issue? I'm getting this warning in a random manner.Any suggestions?Thanks. Sometimes, Difficult things are possible...
