I know where the start button is. Clicking my start button doesn't pop up any folders, it brings up a listing of programs and apps.
[Edit] Just tried your desktop folder trick. It works -- sort of -- but I don't like it, and it's not at all the same as having program groups like in WFW 3.11. Yes, I could create a new folder, and I was able to drag some icons into it. Bu then when I clicked on the new folder, it didn't open a program group window -- it opened File Manager. The program icons were in there -- after I modified the settings to show other than "Details," which is my preferred and default setting for all folders. But "large" icons are too small, and 'Extra large" icons are just small icons in a larger square, white box.
In fact, I mis-stated when I said I didn't know about this trick. Once I did it, I remembered that I tried it several years ago. I didn't like it any better then than I do now. The new, sample folder has been deleted and my desktop has been restored to the way it was.
