How to Fix Webcam Not Detected After a Windows Update

Webcams have become an essential part of daily life—whether you’re working remotely, attending online classes, or just catching up with friends and family over video calls. But what happens when your webcam suddenly stops working right after a Windows update? For many users, the dreaded “No camera detected” error appears, leaving them stuck without video access.

If your webcam isn’t detected after a Windows 10 or Windows 11 update, you’re not alone. This guide will explain why this happens, walk you through practical troubleshooting steps (with error code examples), answer common FAQs, and point you toward credible resources like Microsoft forums and Reddit where users share real-world fixes.

Why Isn’t My Webcam Detected After an Update?

When Windows installs updates, it sometimes changes drivers, privacy settings, or core system files. This can interfere with webcam detection. Common causes include:

  1. Driver conflicts – Updates may install generic drivers that don’t work well with your specific webcam.

  2. Disabled camera privacy settings – After an update, Windows may disable camera access by default.

    • Antivirus or security blocks – Security software may misinterpret webcam usage as suspicious.

  4. Corrupted drivers – If an update interrupts installation, drivers may become corrupted.

  5. Hardware compatibility – Older webcams may not be fully supported by new Windows builds.

Step-by-Step Troubleshooting

Step 1: Check Error Messages

Sometimes, you’ll see errors such as:

  • “No camera found”

  • “We can’t find your camera (Error code 0xA00F4244)”

  • “0xA00F4292 – Camera busy”

These codes help identify whether it’s a hardware detection issue or a driver/software conflict.

Step 2: Verify Privacy Settings

After updates, camera access might be disabled.
