Thanks for both the poster and the answer from Tiger.
Just question for the poster:
When we creat a new Key with the value of "Recycle Bin" on the NameSpace pane, there is an existing Key with the same value already. Does it conflict or we need to delect the existing one?
The question for Tifer:
Just be sure that if we double click the Recycle.reg that we create, it will be added to the regular path of the Registry and is it conflict or harmful for regular Recycle operation?
