Fresh Start lets you perform a clean reinstallation and update of Windows while keeping your personal data and most Windows settings intact. In some cases, a clean installation may improve your device's startup and shutdown experience, memory usage, Microsoft Store apps performance, browsing experience, and battery life. Fresh Start
To use Fresh Start, select Start > Settings > Update & security > Windows Defender > Device performance & health. Under Fresh Start, select Additional info > Get Started.
Note: Fresh Start will remove most of your apps, including Microsoft Office, third-party anti-virus software, and desktop apps that came pre-installed on your device. You will not be able to recover removed apps, and will need to manually reinstall these apps later. You may also lose your digital licenses and digital content associated with apps, which may impact your ability to use these apps or app-related content you paid for.
Fresh start is available for Windows 10 versions prior to 2004. For version 2004 and after, Fresh start functionality has been moved to Reset this PC. To reset your PC, go to Start > Settings > Update & Security > Recovery > Reset this PC > Get Started. Then, select Keep my files, choose cloud or local, change your settings, and set Restore preinstalled apps? to No.
Note: If you don't see the option to Restore preinstalled apps, it means your PC doesn't have preinstalled apps configured and won't restore apps from your PC manufacturer.
