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.
We always try to inform about such problems. For many readers, today’s article will still be relevant, since Microsoft issued a bad update only yesterday, it has not yet arrived at all, or has not yet been installed.
Windows 10 KB4549951 update
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. Here are some problems encountered by users:
I updated my Windows 10 on 15.04.20 (KB4549951). Bluetooth stops working after the update. It is not shown in the Bluetooth Device Manager now. I tried to uninstall the updates but it still doesn’t appear. What to do now? My Laptop supports Bluetooth!
“After this update, my computer cannot connect to the internet. I can see the wifi adapter in the device manager and there is no reported problem. There is no network available to connect. ”
Judging by the fact that the patch is still available, Microsoft has not yet pulled the update. For users who did install it already, fortunately, Microsoft allows users to uninstall Windows updates that are not suitable for them.
