How to fix face driver/ face recognition, Elan fingerprint, and integrated camera which is not there anymore

Subject: Request for Restoration of Windows Hello Functionality on Dell Inspiron 16 Plus 7640

Dear Microsoft Support,

My name is Gwen Harrell, and I’m reaching out for assistance restoring biometric functionality on my Dell Inspiron 16 Plus 7640, which I purchased on May 5, 2025 with active Pro Support. The device was marketed as fully compatible with Windows Hello, including both facial recognition and fingerprint login — and upon first use, both features worked properly.

However, an interrupted BIOS and firmware update caused the system to restart unexpectedly, leaving the update process incomplete. Immediately afterward:

The integrated webcam failed to register for facial recognition
Windows Hello reported biometric features as “currently unavailable”
The system architecture and biometric provisioning appeared fragmented

🧠 Key Findings from My Investigation

I’ve put extensive time into identifying the problem and discovered the following:

My system is powered by an Intel Core Ultra 9 185H processor (confirmed x64 architecture)
I found biometric provisioning executables, including WinBioDataModelOOBE.exe, which confirms facial recognition had been correctly set up
OneDrive auto-sync migrated files and drivers from previous ARM64 Dell devices, contaminating the biometric environment
The driver stack became misaligned due to those ARM-based components entering an x64 system
My Windows Product ID later shifted to OEM, and Dell concluded facial recognition wasn’t supported

Despite fingerprint login being intermittently restored using the October 2024 ELAN driver, facial recognition was never re-enabled, and Dell ultimately removed it from the biometric stack entirely — without reinstallation or repair. They recently returned the device without performing any corrective action.

❌ New Problem: Network Failure

After the device was returned, it also began experiencing network connectivity issues, possibly due to a corrupted or missing Wi-Fi driver. I’ve attempted multiple resets and updates, but the system continues to fail to connect.

🎯 What I’m Asking For

I would sincerely appreciate your help with the following:

Confirm that my system and integrated webcam support Windows Hello facial recognition
Provide guidance to restore HelloFace drivers and biometric provisioning files appropriate for my x64 architecture
Assist with resolving the network issue potentially caused by Dell’s incomplete support action

I am not asking out of frustration — I’m reaching out because I’ve taken every careful and informed step I could, and I truly want to restore my system to the condition it was in when I first opened the box on May 5. I am happy to provide screenshots, diagnostic logs, and a full timeline of events if needed.

Thank you for your time and consideration, and for helping me bring my device back to full, intended functionality.

Warm regards,
Gwen Harrell

Dear gwen harrell

Thank you for reaching out. I'm Haien from Q&A Forum. Welcome to Microsoft Q&A Forum.
Thank you for reaching out to Microsoft support! I’m so sorry to hear about the issues with your Dell Inspiron 16 Plus 7640, especially after the interrupted BIOS update and the subsequent loss of Windows Hello facial recognition, fingerprint login, and now network connectivity. It’s great that you’ve documented this so thoroughly, and I’m here to help you restore your device to its full functionality as it was on May 5, 2025, when you first purchased it with active Pro Support. You've done an impressive job diagnosing the problem yourself, from identifying the WinBioDataModelOOBE.exe confirming initial setup to suspecting the ARM64 driver contamination from OneDrive and the resulting driver stack misalignment.

However, based on your description, I can determine that the problem you are having may come from the software in the Dell computer system you are using - the problem is not necessarily from the Windows operating system you are using. Therefore, for your convenience, I hope you can contact the laptop manufacturer you have to confirm whether the problem is with the Windows operating system or the laptop system.

To help you further, please let me ask a few questions so I can provide to you more suitable questions:

Can you confirm if the webcam has an IR light (small red dots near the lens) for facial recognition?
Did the network issue start immediately after the device was returned, or after a specific action?
Are you seeing any error codes in Device Manager or Event Viewer for the camera/biometrics?

Here are some effective ways that you can try to fix the problem:

Solution 1: Check Windows Hello Compatibility

Step 1:

Check your device specs on the Dell support site using your service tag (found on the bottom of the laptop or via Settings > System > About).
Look for a Windows Hello-compatible infrared (IR) camera—some Inspiron 16 Plus 7640 models include it, though some (e.g., with integrated graphics only) may not. If confirmed, proceed; if not, this may explain Dell’s stance, and we can explore workarounds.

Step 2:

Settings > Accounts > Sign-in options > Under "Ways to sign in," check for "Face recognition (Windows Hello)" and "Fingerprint recognition (Windows Hello)." >
If they are now available (not "currently unavailable"), click on them and select "Set up." > Follow the on-screen prompts to enroll your face and fingerprint.
If they still show "currently unavailable," try troubleshooting using the built-in Windows Hello troubleshooter:
Go to Settings > System > Troubleshoot > Other troubleshooters > Look for "Windows Hello" or "Biometric" related troubleshooters > run them.

For additional information, please visit this article: Configure Windows Hello - Microsoft Support

Solution 2: Run the Windows Hello Troubleshooter

Navigate to Settings > Accounts > Sign-in options. If Face Recognition is showing as currently unavailable, run the built-in troubleshooter by going to Settings > System > Troubleshoot > and look for any Biometric related troubleshooters to run.

Solution 3: Reinstall Biometric Drivers – Clean Install

Step 1: Uninstall

Device Manager (right-click Start button) > expand Cameras and Biometric devices > Uninstall any existing webcam and fingerprint drivers (e.g., ELAN)
Or Device Manager (right-click Start button) > go to View > Show hidden devices > Expand "Cameras" > Locate your integrated webcam (e.g., "Integrated Camera," "Intel(R) IPU6," or similar) > Right-click on it and select "Uninstall device."

Step 2: Remove Biometric Devices and Remove USB Devices

Device Manager (right-click Start button) > Expand "Biometric devices." > Locate any entries related to "Windows Hello Face Software Device," "Windows Hello Fingerprint Sensor," or your ELAN fingerprint sensor. > Right-click on each entry and select "Uninstall device." > check the box "Delete the driver software for this device" if prompted.
Device Manager (right-click Start button) > Expand "Universal Serial Bus controllers." > look for "USB Composite Device" or "Unknown USB Device" > Right-click and "Uninstall device"
Restart PC

Step 3

Visit the https://www.dell.com/support/home/ for your Inspiron 16 Plus 7640, enter your service tag, and download: Latest Intel Integrated Sensor Solution Driver (for webcam/IR) and Latest ELAN Fingerprint Driver (October 2024 or newer) > Install drivers in order
Reboot > set up Windows Hello again (Settings > Accounts > Sign-in options).

Note/Warning: Back up data before uninstalling—ensure a stable connection during install. When doing a clean driver install (especially after a Windows reset), install Chipset drivers first, then Intel Management Engine, then Graphics, then Audio, then Network (Wi-Fi/Bluetooth), then USB/Biometric drivers.

The network working it was a modem issue

Vanishing Hello: When a Firmware Update Silenced My Camera’s Identity

Until recently, my Dell Inspiron 16 Plus 7640 had a webcam setup that worked beautifully with Windows Hello facial recognition. It wasn’t an infrared camera — it was something better in many ways: a depth-enhanced RGB webcam with software-based 3D mapping that passed Windows Hello’s requirements with flying colors.

The login process was seamless. Secure. Reliable. And critically, my system displayed full ESS (Enhanced Sign-In Security) — confirming the camera wasn’t just compatible, but participating in an elevated authentication framework.

Then Dell Got Involved…

After a BIOS change and firmware intervention, Dell removed the integrated camera from my stack. What followed was a silent unraveling:

The camera vanished from Device Manager

HelloFace provisioning was gone

And that clear “ESS enabled” status? Completely missing.

🔍 Not an Incompatibility — A Cutoff

This wasn’t a case of Windows Hello “no longer being supported.” It worked before. It was provisioned before. The camera was fully recognized and integrated before. What changed was Dell’s firmware update — which removed the depth stack and failed to restore it afterward.

The system didn’t reject Windows Hello. Dell cut off the depth recognition pipeline, and Windows Hello was left in the dark.

Dear gwen harrell

Thanks so much for the update and for the detailed information. I am so sorry for the late reply. It's incredibly helpful to know the network issue is resolved—that's one less thing to worry about!

Your discovery about the camera is a game-changer. The fact that you had a depth-enhanced RGB webcam with software-based 3D mapping is a crucial detail that explains why your system initially supported Windows Hello Facial Recognition. You're right; this isn't an incompatibility issue, but a disruption caused by the firmware update and subsequent actions.

From the information you have provided, I can see that your camera issue is a Dell issue. We at Microsoft are sorry that the issue you are experiencing is beyond Microsoft's control as it is a manufacturer issue for the device you are experiencing. So please stay tuned if you can get a new device to continue with your laptop or if the Dell camera you have is repaired and update me if you are still experiencing the same issue.

Your satisfaction is Microsoft's priority

Your laptop doesn't have infrared camera or any depth camera, so there is no windows hello face.

In adddition

Win11 by default only installs critical security updates, unless you made the mistake of selecting “Get latest updates” which includes drivers.

See your laptop/PC makers support to update both bios and makers drivers.

There should be a shortcut to that makers update utility on your system.

Then set Bios to defaults & Pwr to balanced. At the end of the day shutdown, do not leave in sleep.

Do NOT update from any other source inc Device Manager

You only need to set the Advanced options for notify & Time, then leave win update to do its own thing.
