Windows 10 blue screen (BSOD) when starting the camera / webcam, SPUVCbv64.sys

With the recent Windows 10 feature updates to version 1909 and version 2004, some webcam models have started causing blue screens (BSOD) in Windows 10.

We have observed this happening especially for webcams using drivers from a company called Sunsoft IT or something similar.

Fortunately, there is a solution available.

  • Open the Device Manager and right click the webcam -> Properties
  • Click Update Driver
  • Browse my computer for drivers
  • Let me pick from a list of available drivers on my computer
  • On the final screen, choose Microsoft USB device

This will replace the faulty driver with a Microsoft equivalent and hopefully your computer will no longer crash when starting the webcam.

The easiest way to verify that the problem is gone is to start the built in Windows 10 app “Camera” by searching for “Camera” in the Start menu

    • I really hoped this would work. On my HP laptop (ProBook 4540s), there is no final screen that shows Microsoft USB device. Step 4 led me to a screen where I could choose the device I wanted to update, with a choice of “Have Disk” (which I don’t want to mess around with, and anyway I don’t have a Win10 disk) and then it said it updated the driver. It also told me to restart my computer. But after I restarted and tried out the camera, it still gave me the BSOD, same thing.

  1. Many, many thanks!! Wish I had just looked up your information instead of spending a few worthless hours on the phone with Microsoft. This was easy and helpful!

  2. Problem finally solved when I sought help from Microsoft virtual agent on windows 10, who installed Microsoft driver for me. Thanks to Microsoft!

      If the camera doesn’t show up there, look for something named “Unknown device” further down in the Device mgr. It could also be that your camera is disabled in the laptops BIOS

    Thanks for this in-depth review. I was looking for information about this but didn’t get any information what exactly
    I am looking for. Fortunately, I come across to your website and it helps to make my decision.
    It’s really made my day.
    Thank you again for this great article.

  4. Brilliant! Have this Lenovo Ideapad with built in webcam. BSOD all the time. Did all the recommended driver updates, Windows updates… useless. This neat trick was all it took. Unbelievable messy business!
