When the wizard hangs, the Task Manager Applications tab shows the Scheduled Task Wizard as Not Responding, and the Processes tab shows that Explorer.exe is using between 96 and 99 percent of the CPU cycles.

This behavior can occur if the NTFS permissions for Everyone and Users have been removed from the "%ALLUSERSPROFILE%\Start Menu" folder, usually "C:\Documents and Settings\All Users\Start Menu".

NOTE: The permissions may also have been removed from sub-folders. When I run CACLS "%ALLUSERSPROFILE%\Start Menu", the following is returned:

To fix this problem, an administrator should use Windows Explorer to right-click each All Users sub-folder and set the permissions, or use the Advanced tab to check the Inherit from parent the permission entries that apply to child objects. Include these with entries explicitly defined here box.

NOTE: The administrator could right-click the All Users folder, verify its' permissions, and then select the Replace permission entries on all child objects with entries shown here that apply to child objects box on the Advanced tab.
