Modifying Registry Using VBScript

I am trying to write a vbscript utility that will add or remove开发者_StackOverflow several related registry keys. However, I cannot seem to find a code that will work.

What is the code for removing a registry key? What is the code for restoring a key (with values)? Thank you!
