As you save new files, update files, and delete files, or install and uninstall software, over time, your computer can become a bit sluggish.
With Windows 10, Microsoft have included a feature called ‘fresh start’ that allows you to re-install Windows 10 without deleting any of your files. Fresh start will remove windows setting and installed apps. As always, before performing any operation you should have a backup of all your files in case things go wrong.
