My hello sign in stopped working.

Hi,

This problem that started after installing the last Windows update might be caused by outdated or corrupted device drivers. For us to better assist you, we'll be needing additional information:

• Are you pertaining on Windows Hello sign-in? If yes, does it mean that the facial recognition is not working?
• Is there an error message displayed when using Windows Hello?

Meanwhile, it is better to check the status of Windows Hello sign-in option in your computer. To check the Windows Hello status, follow these steps:

• Click the Start button and select the Settings
  icon.
• Choose Accounts from the list.
• Select Sign-in options in the left pane of the window.
• Under Windows Hello, kindly check the status of it.

As an initial troubleshooting step, we suggest keeping the device drivers like camera driver up-to-date. For your reference, check this article on how to

Hi Ameera,

Thank you for writing to Microsoft Community Forums.

We understand how difficult it could be when feature do not work the way they supposed to and we truly appreciate the time and effort that you have taken to work on this issue. This issue can occur if the camera driver is not updated or due to some hardware
issues related to the camera. In order to isolate the cause of this error, please follow the methods mentioned below.

Method 1: Check if the camera is working.

1. Log in to the system.
2. Go to Start menu and select Camera app.
3. Check if the camera is working fine.
4. If not, please update camera driver (you can refer
   Update drivers in Windows 10 for the steps).

Method 2: Troubleshoot problems with Windows hello.

Since you are getting the error "Couldn't start camera. Please sign in with PIN", we would suggest you to refer

Troubleshoot problems with Windows hello Surface under the section Windows Hello doesn't recognize my face or fingerprint or there is an error message and try performing the troubleshooting steps and check if it resolves the issue.

Regards.

 

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.
