That depends. Are you having problems with the current version of Windows 10?
If Windows is running ok, you should probably use Windows Update to update it. If you are having problems with Win. 10, you could do a clean install, but you will be getting version 1803. It looks like 1809 isn't available yet on the MS site because they were having problems with the new version. If you do decide to do a clean install and your current windows is working ok, you will have to reinstall any preloaded Lenovo programs that you currently have installed. You should also do a complete backup of your system in case anything goes wrong with the clean install.
