I not sure a reg hack exists for this. Why don't you simply setup the Default User on the machine to use the start menu you want and then use the group policy editor to deny access for people to change the display properties.
This setting effects the presentation of the Start menu.
The classic Start menu in Windows 2000 allows users to begin common tasks, while the new Start menu consolidates common items onto one menu. When the classic Start menu is used, the following icons are placed on the desktop: My Documents, My Pictures, My Music, My Computer, and My Network Places. The new Start menu starts them directly.
If you enable this setting, the Start menu displays the classic Start menu in the Windows 2000 style and displays the standard desktop icons.
CHECK THIS OUT>>>
If you disable this setting, the Start menu only displays in the new style, meaning the desktop icons are now on the Start page.
THIS IS ALSO IMPORTANT>>>
If you do not configure this setting, the default is the new style, and the user can change the view.
The user might SEE the option to change the style, but will be UNABLE to change it.
You obviously don't look very hard. Every aspect of the Windows Desktop can be locked via gpedit. If you are talking about changing the start menu by right-clicking on it, choosing start menu, then choosing classic, that can be locked as well.
GPEDIT-->User Configuration-->Administrative Templates-->Start Menu and Taskbar--> Prevent changes to taskbar and Start Menu settings
Or, to force the style that you want:
GPEDIT-->User Configuration-->Administrative Templates-->Start Menu and Taskbar-->Force classic Start Menu (Disable to force new style).
Group policy is the only way to accomplish what you want. Since the task settings are not controlled in the registry, there is no registry hack. The question I would ask myself is why isn't the group policy editor working? Essentially, it should work fine. Here are some things to consider:
GP in Windows XP only affects non-administrative users. This means that if you set that option (administrator), you can still perform the requested task since you are the administrator on the machine. Try setting the option and logging in as a non-administrative user.
No one here is calling you an idiot. It's just that we know what you are trying to do and are trying to give you the help you requested. If you are say you know and understand something, then that's great. But, you should also know that just because you do know something doesn't mean that you can't learn more about that something.
If you would like me to help you walk through the steps in accomplishing what you are trying to do, feel free to IM me.
It only affects my non-administrative users. But then again, I did change the settings on it. I guess that by default, it does affect admin. But anyway, it works for me here, so I'm not sure why it doesn't work for you two.
Sorry, I'm a annoyed by this because I tried this with GP and I've tried all user groups, it doesn't take effect. Other settings do. Just the options that I found and that you listed off do no disallow the user to change to the classic menu.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
