Hello DonaldBarnhart05,
Thank you for reaching out Surface Community. The PrtScn Key is designed for copy and paste the "screenshot" in a specific document like Word, OneNote, etc... But if you'd like to save the PrtScn as a File you should use the combination Fn Key + Windows Key + Space Bar or Windows Key + PrtScn. The file will be save to This PC > Pictures > Screenshots.
Best Regards,
