How to format my laptop and keep my windows as well as dopustomisatoon softwrae by the brand of maufacture

So I have a legion 5 with an RTX 3060 and an i7-12700h and I have been encountering some performance issues with it. I have been pirating stuff so I was wondering how can I reset the pc and keep the windows key that came with it and how can I install the customisation software by Lenovo such vantage.
