unfortunately u can't simply rename registry key, u need to copy it, then delete the old one.
here code snippet to do so:
public bool RenameSubKey(RegistryKey parentKey, 
			string subKeyName, string newSubKeyName)
        {
            CopyKey(parentKey, subKeyName, newSubKeyName);
            parentKey.DeleteSubKeyTree(subKeyName);
            return true;
        }

        /// <summary>
        /// Copy a registry key.  The parentKey must be writeable.
        /// </summary>
        /// <param name="parentKey"></param>
        /// <param name="keyNameToCopy"></param>
        /// <param name="newKeyName"></param>
        /// <returns></returns>
        public bool CopyKey(RegistryKey parentKey, 
			string keyNameToCopy, string newKeyName)
        {
            //Create new key
            RegistryKey destinationKey = parentKey.CreateSubKey(newKeyName);

            //Open the sourceKey we are copying from
            RegistryKey sourceKey = parentKey.OpenSubKey(keyNameToCopy);

            RecurseCopyKey(sourceKey, destinationKey);

            return true;
        }

        private void RecurseCopyKey(RegistryKey sourceKey, RegistryKey destinationKey)
        {
            //copy all the values
            foreach (string valueName in sourceKey.GetValueNames())
            {        
                object objValue = sourceKey.GetValue(valueName);
                RegistryValueKind valKind = sourceKey.GetValueKind(valueName);
                destinationKey.SetValue(valueName, objValue, valKind);
            }

            //For Each subKey 
            //Create a new subKey in destinationKey 
            //Call myself 
            foreach (string sourceSubKeyName in sourceKey.GetSubKeyNames())
            {
                RegistryKey sourceSubKey = sourceKey.OpenSubKey(sourceSubKeyName);
                RegistryKey destSubKey = destinationKey.CreateSubKey(sourceSubKeyName);
                RecurseCopyKey(sourceSubKey, destSubKey);
            }
        }

The above code is just a class i presume  and i would need to define these in another piece of code.
Thanks in advanced. Just trying to understand where to start
