goto:eof

let say my computer have a the same folder in the registry but different value. by using this command it wont merge it. so how do i actually add in a merge with this ?

By folder I assume you mean Key. The /f parameter you use should overwrite any current value. Are you saying that doesn't work?

If you remove /f and a value already exist for a key, you'll be prompted if you want to overwrite the current value. That's a good way of testing this.
