What software are you using to see the information?
Are you talking about when right clicking on an image using Windows Explorer?
If so, you may have missed a step (Advanced).
To see EXIF, "right click" on a file in Windows Explorer, and select Property, Summary, Advanced. But, it doesn't show you WB settings or some of the manufacturer specific info.
Yet another way to view EXIF is using IExif from Opanda. When you right click on an image in Windows Explorer, you'll see a new choice for viewing EXIF after you install it. It also works with Internet Explorer.
After loading it, you can also install a plugin for Firefox so that you can see EXIF in images using Firefox without downloading them. I use it often for looking a camera settings from posted images to check for any obvious problems.

Note, if you have changed the images in any way, the software you used for editing or downsizing may have stripped out the EXIF. For example, Photoshop will strip out this information if you use the Save for Web option.
