Is there a setting I can activate so that when I label a picture it do

Also, in reading through the steps, it appears that the Reset reg must be run first, the machine restarted, then the disable reg. Did you exactly follow steps 1-9?

I just tried it with Extra large icons and it did not work.
How do I know if it is in a library?

Are the images saved to your user Pictures folder? If your unsure, try creating a new folder on any drive. If you use C:\, be sure you are not creating it inside the Users folders.

Another, perhaps simpler option (although more limiting than the Auto-Arrange Disable) is to simply change the sort order in explorer, i.e., instead of sorting on name, you could sort on date or any other column setting you choose (and you can add any of the many column choilces by right clicking on on of the column headings and choosing from the list). This method will work in Libraries. In conjunction with the Arrange By options, you may find something to suit you.
