Hi Meme. I'm Greg, a volunteer installation specialist and 8 year Windows MVP, here to help you.
Is this an HP which has SimplePass software installed? If so it can generate this error at Shutdown until it is uninstalled. If you don't use the fingerprint scanner in HP you can uninstall it in Settings > Apps & Features. Otherwise Update the software from HP's Support Downloads webpage using your Serial Number from sticker on PC.
If not that issue then update the touch drivers/software for your PC from the Manufacturer's Support Download webpage.

Post back the exact verbatim error message you're getting.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
