I have to clean a lot of takbars that system created accidentally moving mouse in desktop. It happened bcos PC restarted with a sensors connected to some COM port we are monitoring and W2k though were mouses when restarting

Now desktop has a lot of ramdom taskbars and I can't remove it.
I have read a post ere about how to do it from registry:

but in W2k Server Y can't find that registry key.
Any suggestion about it and how to avoid wrong mouse recognition on startup?
Thanks a lot
