Windows Hello Camera Compatibility/Detectability Issue Cannot detect compatible camera. Worked in the past

Question

So, I'm on week 2 of trying to figure out what's going on with this Windows Hello issue. I spent several hours on the phone with MS support where we did a clean install of Windows 11 and all available updates as well as uninstalled, reinstalled, and updated all hardware and software and we left off at "after the 4th restart your problem should be resolved." I can't tell. I don't know exactly why or what started it obviously, but it worked fine prior to this. I've tried to find out what the factory drivers are but Lenovo's website has proven difficult to navigate but also could've been because I use Opera. Just thought about that. If any of you could help me through this it would be very much appreciated! Much Love & Gratitude!! Namaste 🙏

Follow these steps in order, checking Windows Hello after each major step:

1. Confirm the device actually supports Windows Hello Face

• Some devices do not support facial recognition at all. For example, Surface Laptop 13-inch 1st Edition and all Surface Laptop Go models do not support Windows Hello Face and must use fingerprint or PIN instead.
• On the Lenovo device, check the model’s specs on Lenovo’s support site to confirm it has an IR camera that supports Windows Hello Face. If it does not, use PIN or fingerprint instead of face.

2. Re‑set up Windows Hello Face If it used to work and now says it cannot find a compatible camera:
3. Sign in with PIN or password.
4. Go to Start > Settings > Accounts > Sign-in options.
5. Under Facial recognition (Windows Hello):
   • If it shows Remove, select it to remove the existing face data.
   • Then select Set up and follow the prompts.
6. If it shows Improve recognition, use that to rescan the face, especially if lighting or appearance (e.g., glasses) has changed.

Details from the guidance:

• If the message is “Couldn’t recognize you. Please sign in with your PIN”, use Improve recognition under Facial recognition (Windows Hello) to rescan in current lighting and with/without glasses as needed.

3. Make sure Windows and camera/firmware are fully updated For devices that support Windows Hello Face:
4. Go to Start > Settings > Windows Update and install all available updates.
5. Install any Lenovo firmware/camera driver updates from Lenovo’s support site for the exact model.
6. Check that the camera itself works in Windows
7. Open the Camera app and verify that video from the built‑in camera appears.
8. If the camera does not work or shows errors, follow these steps:
   • Try a different USB port if using an external camera.
   • Open Device Manager (search for “device manager”).
   • Look under Cameras, Imaging devices, or Sound, video and game controllers for the camera.
   • If the camera is missing, use Action > Scan for hardware changes and then restart.
   • If the camera appears but is not working, check for driver issues:
     • Right‑click the camera > Properties > Driver > Driver Details. If a file with stream.sys appears, the camera is too old (pre‑Windows 7) and is not compatible; it must be replaced.
     • If the camera stopped working after an update, try Properties > Driver > Roll Back Driver, then restart and test the Camera app again.
9. Check for incompatible or generic drivers If the camera is present but unreliable:
10. In Device Manager, right‑click the webcam > Update driver.
11. Choose Browse my computer for drivers.
12. Choose Let me pick from a list of available drivers on my computer.
13. Select USB Video Device and select Next.
14. Close and restart.

Note: The in‑box USB Video Device driver may not support all camera features. In particular, Windows Hello Face might stop working if the manufacturer’s driver provided special extensions. If that happens, reinstall the Lenovo‑provided camera driver instead.

6. Run the Windows Hello troubleshooter (if available) If the device supports Windows Hello Face and the camera works in the Camera app but Hello still fails, run the dedicated troubleshooter for Windows Hello Face recognition:

• Use the Run Windows Hello troubleshooter link from the Windows Hello troubleshooting article to let Windows attempt automatic repair.

7. Consider known Windows 11 24H2 camera issues If running Windows 11, version 24H2, be aware that some devices had issues where integrated camera use (including Windows Hello) could cause apps to become unresponsive. This was resolved by updated drivers delivered via Windows Update. Ensure all updates are installed and restart the device; it can take up to 48 hours after the fix for the update to be offered.

If, after all of the above, Windows Hello still reports no compatible camera but the Lenovo documentation confirms the device has a Windows Hello–capable IR camera and the Camera app works, the remaining likely causes are:

• Missing or incorrect OEM camera/IR driver (reinstall from Lenovo support for the exact model).
• Hardware fault in the IR sensor (requires Lenovo hardware diagnostics and possible repair).
