separate explorer and desktop

Hi,
Does anybody know how separate the explorer process and desktop in Windows 2000?
When you have a problem with a explorer window and you kill it using task manager the desktop "reset" too.
I know that it is possible changing a parameter in windows registry because I read, it but I don´t remenber it.
Thanks

I may be wrong here, but try looking for "Launch folder windows in separate process" in the folder settings.
