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.
