Description
Removes the shortcut bar from the Open dialog box.
This policy, and others in this folder, lets you remove new features added in Windows 2000, so that the Open dialog box looks like it did in Windows NT 4.0 and earlier. These policies only affect programs that use the standard Open dialog box provided to developers of Windows programs.
Tip
To see an example of the standard Open dialog box, run Notepad and, from the File menu, click Open.
