Hi

Try...

Yes — in Windows 11 the quickest way to list installed drivers is with Command Prompt or PowerShell. driverquery shows a full list of drivers, and Device Manager lets you inspect drivers device by device.

Open Command Prompt as administrator and run:

That lists the installed drivers in columns such as module name, display name, type, and link date.

To export the list, run:

That creates a text file you can search later.

Even better is my old favourite............

Open Windows Terminal / PowerShell as Administrator and run:

This saves a CSV file on your Desktop with the verbose driver list.

Better CSV with more control

If you want more readable columns, use PowerShell:

This exports a CSV containing common driver details such as device name, version, provider, date, and INF name.

Then, of course, open it with LibreOffice.

Don't be surprised if you see drivers for a parallel port (parport) and other obsolete stuff.

Tnx Ann but as stated, I already copied all the drivers from the driverstore.  Using the RAPR tool is much easier than command line.  Getting the drivers is not the problem.

I was hoping someone from Dell would be interested to have
1) a copy of the full driverstore that does work on the XPS 14 including the camera
2) a copy of the driverstore that Dell Support Assist fails to fix for the XPS14 with camera, sound and mic not working.

This will allow them to see which drivers are causing the problems and fix Dell Support Assist to get it to install the correct drivers.

Hi  DELL-Nat M

Please explain to the team that facial recognition requires a working internal webcam to take a picture of your face. 
1) In the case of 1 above the camera is working
2) In the case of 2 above, the internal webcam is NOT BEING DETECTED, the webcam is NOT WORKING and it is therefore IMPOSSIBLE for facial recognition to work. 

Hi

The intent was to compare the list of installed drivers.....

""I have made a copy of the Win 11 driverstore of the installation that works and another one of the installation where the drivers fail. Is there anyone that can assist in determining which drivers are causing this?""

I assumed that when you stated you had/have an install that works, and an install that don't, a comparison would be beneficial.

However I realise I don't know where/which "Win 11 driverstore" you are referring to.

However the clean install must have a list of drivers that make the camera work, and yet again it's an assumption, that an update, either a W11 or installing a piece of software to use the camera is where the problem lies.

SO a before and after driver listing with driverquery will show any W11 changes and hopefully pinpoint the problem, or at least remove W11 from the equation.

But what do I know about anything?

@PeterMousetail That sounds incredibly frustrating, especially after going through multiple repairs and still ending up with the same issue—it really does point toward a driver conflict rather than hardware at this stage. I’ve seen similar situations where a clean system behaves differently simply because of hidden driver mismatches or corrupted configurations, so your approach of comparing driverstores makes total sense.

Thanks gailhamilton. Yes, I have copies of the 2 sets of drivers and I thought that someone from Dell Support would be keen to analyse and compare. This will enable them to fix SupportAssist which is unable to find or resolve the problem. This is further aggravated by the XPS 14 firmware not having a function to test the camera (unlike the sound for example).   Therefore, the conclusion of Dell support is to send out a tech to do hardware replacement while the problem is in fact related to driver mismatch.

Unfortunately, the service level of Dell is not what it used to be.  Buying a support package having a 3 day on-site turnaround it not worth anything if they have not been able to fix this in 4 months.  No surprise that Dell sales of laptops are declining while Lenovo increased sales by 20% YoY with a market share of 27% (Dell 18%).  Guess what brand my next laptop will be.

Hi I have a similar situation making the Webcam works on a similar, XPS 14 DA14260

On my side I know it's not an hardware failure since I restored system with OS recovery and the webcam works fine from the factory Dell image.    Trying to make the webcam work from our custom corporate image is being a nightmare so far.  

Still have hidden devices without driver: USB4\VIRTUAL_POWER_PDO&VID_8086&PID_E433&REV_0001

USB4\VIRTUAL_POWER_PDO\4&1EDC24B6&0&0

Webcam on the driver side looks fine, it's listed but  fail to work after few second.

There is mention in the eventvwr sorry for the French interface.

@AndreR0y​ , I have given up. I use a Logitec external webcam that works. 

Hi

It's unlikely that I have/will post anything useful, but that wont stop me....

Likely root cause

Given the components involved, this is almost certainly:

• Intel camera driver issue (very common with newer Windows builds like 24H2 / 26100)

• Triggered when something accesses the webcam:

  • Camera app

  • Teams / Zoom

  • Browser (WebRTC)

  • Windows Hello (if camera-based)

This matches with a few seconds of usage?????????????????????

Practical interpretation

In plain terms:

Windows’ camera service (FrameServer) crashed because the Intel camera driver DLL tried to access invalid memory.

What I would check (based on your background)

Given your experience, the useful angles are:

• Driver version alignment

  • Version 71.26100.0.20219 suggests a relatively new OEM or Windows Update driver

  • These sometimes regress on specific hardware revisions

• Device Manager → Cameras / Imaging devices

  • Check if this is Intel IPU / MIPI camera (common on newer laptops)

• Event correlation

  • Look for:

    • Event ID 1000 (Application Error)

    • Event ID 1001 (Windows Error Reporting)

    • Any Kernel-PnP or camera stack warnings before it

Fix approaches (in order of likelihood)

• Roll back the Intel camera driver

• Install OEM driver from Dell/ASUS instead of Windows Update

• Clean reinstall:

  • Remove device + tick “delete driver”

  • Reboot and reinstall manually

• Disable Frame Server (for testing only):

  • Registry:
    HKLM\SOFTWARE\Microsoft\Windows Media Foundation\Platform
    Set EnableFrameServerMode = 0 (DWORD)

• If reproducible with a specific app:

  • Try forcing different capture backend (e.g. in OBS or Teams)

If this happens when opening Teams:

• Teams requests camera

• FrameServer spins up inside svchost

• IntelDeviceMFT64.dll processes the stream

• DLL hits invalid memory → crash

• Camera fails or app freezes briefly

Probably what you already know and tried to fix.
