Task Boot

As if there were few problems with sound and missing files. A recent update to the Windows 10 operating system turned out to be far more problematic than it initially seemed.

Microsoft released on May 12 the traditional “Patch Tuesday” update under KB4556799 for Windows 10 versions 1903 and 1909. The update was supposed to increase the security of Internet Explorer and Microsoft Edge browsers, the use of Microsoft Xbox and Microsoft Office suite products, and so on.

However, users encountered a number of troubles after installing the update KB4556799. We already wrote about problems with sound and missing files. But this was not the end of the matter. Complaints about the upgrade range from the collapse of the BSOD blue screen of the death system to the replacement of system fonts in Outlook. 

Here is a typical complaint:

Last night, the last thing my computer did before shutting down was installing KB4556799 and KB4552931. This morning, the “blue screen of death” appeared twice in 10 minutes. Each time I used a browser (the first time – Firefox, the second – Chrome). I did not have time to see what error message was issued, because the “blue screen of death” appeared too quickly. “

At the moment, all these problems are solved only by radical removal of the installed update. Microsoft is now focusing on the major Windows 10 May 2020 Update (version 2004), which will be available to ordinary users in late May. 

Windows 10: April patch causes a scary blue screen of death

Unfortunately, errors in Windows 10 are not uncommon, but basically they are not serious. But there are errors that lead to crashes and the “blue screen of death” (BSOD). And it is currently not uncommon with the update number KB4549951.

Microsoft released update KB4549951 a week ago. This should actually fix the problem where the updates for the Windows 10 releases of 1903 and 1909 failed. But, unfortunately, there was a classic case of improvement in the worst, possibly worse.

Windows 10:  KB4549951 can cause serious problems

Already last weekend there were reports of the first problems. A reported including crashes, connection problems with WLAN, as well as Bluetooth and poor system performance. Unfortunately, this is not all. Because, according to Windows Latest, some users are currently experiencing system crashes and freezes after installing KB4549951. Which are reflected in the Blue Screen of Death.

Unfortunately, this BSOD is also quite common. If you get such a blue crash screen. You can see various stop error codes. However, they are complex and do not seem to follow a specific model. The following error codes are reported:

• PAGE_FAULT_IN_NONPAGED_AREA
• CRITICAL_PROCESS_DIED
• ACPI_BIOS_ERROR
• INACCESSIBLE BOAT DEVICE
• MEMORY_MANAGEMENT
• DPC_WATCHDOG_VIOLATION
• Portcls.sys

This can happen, among other things, with damaged installation files, drivers, and compatibility issues with third-party software. So there is no obvious source of the error. Microsoft does not currently fix the problem or issues. In this case, victims should remove the cumulative update for April. However, in this case, they are no longer protected by the latest security updates. If you can no longer access the desktop, you must start the computer in safe mode.
