I find the following location in the registry has info about the tasks in
the schedular.
HKLM\SOFTWARE\Microsoft\WindowsNT\Current Version\Schedule\TaskCache
for me the task with value {CD899A53-4BAD........} referenced the schedule
task. Getting rid of all entries the reference that value got rid of the
error messages for me.
WARNING these entries are owned by SYSTEM you can delete them but you cannot
change them and you cannot create them.
MAKE SURE YOUR HAVE CREATED A RESTORE POINT BEFORE MUCKING IN HERE.
This does not seem to be the ONLY place that has info, even after deleting
the entries and schedule folder in regedit, the folder exists and is not
'empty' in task scheduler and cannot be deleted nor can the origional task
name be added (already there).
