I'm trying to create a custom start menu for different users when they logon
at different locations. I've looked at 2 methods:

Use VBScript to redirect the start menu (by changing local registry
settings) to a server based pre-configured start menu. However, this isn't
being updated until the user logs-off and then logs-in again.

I have also tried to use VBScript to copy a pre-defined start menu over the
user's local start menu. However, I am having trouble deleting the Programs
-> Startup and Programs -> Accessories sub-folders. These can be deleted from
My Computer, but can't be deleted with VBScript (or even a Visual Basic app
run by VBScript).

I realise that I can use Group Policy to redirect the start menu, but I'd
rather create a customizable one using VBScript at logon.

Is there a method to force the refresh of the start menu without logging off?
Is there a way to delete the Startup and Accessories folders using VBScript?
