Users claim the update fails to install, causes BSODs
Microsoft published new Windows 10 cumulative updates only a few days ago as part of the November 2020 Patch Tuesday cycle, and naturally, the May 2020 Update, or version 2004, received its very own set of improvements too. These landed as cumulative update KB4586781 and included security fixes when using certain peripherals and the Microsoft Office security suite, as well as improved security when Windows performs basic operations. Microsoft originally said KB4586781 came with just two known issues (a third one for Windows Server was added at a later time), but none of them had anything to do with failed installs or BSODs. And yet, as it turns out, both still happen, and posts online are the living proof in this regard. A Microsoft Answers thread spotted by TechDows, as well as several other complaints published by users on various forums indicate that cumulative update KB4586781 sometimes fails to install, and when it does manage to deploy successfully it actually causes more problems, the worst of which is a fatal crash of the system. Someone on Microsoft’s forums explains that this cumulative update was offered to their new laptop and after installation, the device ended up hitting a BSOD that made it impossible to use it.
