Hi xiaoyun1,
Thank you for reaching out to Microsoft Community.
For installing drivers on our Surface devices, you may use the msi package for your Surface device. Please follow these steps below:
Check what is the current OS Build of your Windows version by going to Settings > System > About.
Go to Download driver and firmware for Surface, choose your Surface device model then click Download on the next page.
Choose the .msi file that matches your current OS Build and click Next.
After downloading, run and install the .msi then Restart.
If the issue you experience still persists after the steps above, please use Troubleshoot problems with Windows Hello on Surface to help resolve the problem.
For help with installing drivers on devices other than Surface, please contact your device manufacturer.
May I know what is this issue that you are having with Windows Hello?
When you go to Windows Settings > Accounts> Sign in options > Windows Hello Face, are you getting an error message? If yes, please share the error message you are getting.
If this helps, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
Kind Regards,
Marrion Y.
