President Ruto appointed six judges nominated by the Judicial Service Commission three years ago, who Mr Kenyatta had snubbed on claims they were “tainted”.
The six judges will be sworn in on Wednesday.
The new president also announced the end of fuel and food subsidies. He said they were costly and ineffective.
Mr Ruto also ordered that all cargo clearance be reverted to Mombasa port – rolling back Mr Kenyatta’s order that saw port services transferred to Naivasha to ensure repayment of a Chinese loan taken for the construction of a railway between the port of Mombasa and the capital, Nairobi.
The orders were part of Mr Ruto’s campaign promises.
