Hi,
Thank you for sharing your question. I understand how worrying it can be when essential features like touch input and the camera suddenly stop appearing in Windows. It can be frustrating to see the touchscreen driver completely missing in Device Manager and to receive the “camera cannot be found” message each time you try to open it.
In most cases, Windows loses access to touchscreen and camera hardware when the system drivers become corrupted, removed, or blocked after an update, reset, or hardware change. Windows 11 relies on the HID‑compliant touch driver and a trusted camera driver to detect these components, so if they disappear from Device Manager, Windows can no longer communicate with the hardware.
You can try resolving this by running Windows Update to reinstall missing drivers automatically, opening Device Manager and selecting “Scan for hardware changes,” checking optional driver updates under Advanced options in Windows Update, and confirming that no privacy or security settings are blocking camera access. If the drivers still do not appear, installing drivers from your device manufacturer’s support website often restores full functionality because OEM drivers include the correct firmware and touch configurations.
May I also ask if your touchscreen or camera ever worked previously on this device, and if you recently installed any updates or performed a reset before the issue began?
Feel free to update me on what you discover or if you’d like help walking through any of the steps. I’m here to support you until everything is working again.
I hope this helps.
Best Regards,
Noel
