Microsoft says Windows 11 update causes BSOD on some GPU config, broke WPA3 Wi‑Fi, but a fix is rolling out
Microsoft has acknowledged two issues with a recent Windows 11 update, one causing crashes on PCs with certain GPU configurations and another affecting WPA3 Wi-Fi connectivity. The GPU bug led to a Black Screen of Death (BSOD) with error code KERNEL_SECURITY_CHECK_FAILURE, which has now been fixed in the February 2026 update. Additionally, the WPA3 Wi-Fi problem, originating from a January 2026 update, is also addressed in the latest update. Microsoft advises installing the updates to prevent system errors and ensure smooth operation.
