To Reset your Windows 10 PC all you need to do is follow these steps, Navigate to Settings on your Windows 10 PC,Select "Update & security", Click Recovery in the left pane, Click Get started under Reset this PC.
Now Click either "Keep my files" or "Remove everything," depending on whether you want to keep your data files intact.
If you want to delete everything click on "Remove everything" but make sure you back up any files you want to keep before clicking remove everything.
In fact it's a good idea to backup all files especially important files and photos, videos etc before restoring your PC.
If you click on Keep my files the files will be in tact after restore.
But if you want to keep every file then just click on keep my files and it may take awhile so be patient but your Windows 10 PC will be reset to like new settings.
