Problems occasionally happen, even for large companies. It’s good when you are warned about them in advance, which is what we are doing now. Recently, Microsoft has released a security patch number KB4549951, which, as it turned out, was unsuccessful. For some users, it causes a blue screen of death, random reboots, problems with Wi-Fi and Bluetooth.
The update is available for Windows 10 versions 1909 and 1903. MSpoweruser notes that this is a security patch, because its installation is recommended, but it’s now in doubt, as it can paralyze the stable operation of the system. In addition to the problems described above, users receive errors with the numbers 0 × 8007000d, 0 × 800f081f, 0 × 80073701, “KERNEL MODE HEAP CORRUPTION” and, in principle, performance degradation.
