Resetting your PC 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 performance, security, browsing experience, and battery life.
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.
In versions of Windows 10 prior to version 2004 this feature was called Fresh Start and to use it you'd select Start > Settings > Update & security > Windows Defender > Device performance & health. Under Fresh Start, select Additional info > Get Started.
Important: Resetting your PC (or using 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. 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.
