I have just installed the Windows 7 in my dell laptop before that I was using the windows vista In that. But after installing the windows 7 I am facing one problem in my laptop. Whenever I open any folder which contains any JPEG.PNG and all video files like avi and mpeg in that I am not able to see the thumbnail view of photo but when I click on it the picture it shows me the normal image. I don’t know what is wrong with the windows 7 is there any case of drivers problem in windows 7? Please reply me with proper solutions.
