A Microsoft spokesman confirmed that the February 2021 cumulative update (KB4601319) came with an error that could disable the webcam.
In addition to camera bugs, users have reported other bugs and Microsoft is reportedly investigating the reports.
According to user reports, the KB4601319 of Windows 10 seem to not support Intel RealSense Depth Camera and Razer Stargazer. Removing the cumulative update solves the problem and some users assume that some virtual driver is missing and it shows after installation of the specific KB.
At the Department supportMicrosoft's “Feedback Hub”, a software engineer said that the company is aware of the problem and is working on some fix.
"Thank you for reporting problems with your Intel Realsense camera Camera. We know the issue and we are working to resolve it. In the meantime, if you want your camera to work, follow our instructions to remove an installed Windows Update. ”
Microsoft may have recognized the problem with the camera, but there are users who they said that KB4601319 also affects the performance of the second wireless mouse screen and other accessories.
In addition to peripheral failure, there are reports of an error causing Blue Screen of Death.
Note that only a handful of users have encountered errors since this month's update and do not appear to be widespread.
In the Feedback Hub, Microsoft said that users can uninstall the February update if they experience problems after installing it. If you can't uninstall it via Windows Update or Control Panel, you can always use the built-in options recoverys or the Media Creation Tool to recover your operating system.
Hopefully the problem will be solved with some upcoming optional cumulative update.
