As users complain of blue screens of death, deleted files and reboot loops, here’s what you need to know about this Windows 10 update.
Patch Tuesday problems unravel
The April 14 Patch Tuesday updates included fixes for a total of 133 vulnerabilities, including seven critical security flaws in Windows 10. I have always said that users need to take the fixing of security vulnerabilities very seriously indeed. When new research suggests that the average Windows 10 PC has no less than 14 weaponized vulnerabilities, that is ones with known exploits in case you were wondering, that seriousness is reinforced.
Indeed, when the April 14 updates were announced, I suggested that users might want to jump the automatic update gun and force a download using the “check for updates” option. I also said that it is “worth backing up your data before installing any update, just in case there are any bugs.”
The trouble, for some, with KB4549951
And bugs there seem to be, with one cumulative security fix, KB4549951, which applies to all Windows 10 version 1903 and 1909 editions. The security vulnerability in question is a denial of service one, CVE-2020-0794, but only impacting users if an attacker had already logged on to your system and then ran a malicious application. So hardly the most critical of vulnerabilities in the overall scheme of security things, you might say. Yet all security vulnerabilities need fixing as any security hole is one too many, and applying updates as quickly as possible is critical to ensuring your systems and data are secure. And that’s where the problems come, according to reports warning of the consequences of installing the KB4549951 update for some users.
Keep calm and don’t patch panic
First things first, given the sheer number of Windows 10 users out there, the number of people complaining of these issues, in the hundreds, is relatively small. This doesn’t make it any better if you are one of them, but it does need to be put into some perspective. The problems those users are reporting to the Microsoft support forums and on social media have included the installation failing and looping back to restart again, the dreaded Blue Screen of Death (BSOD) following a “successful” update and computers that simply refuse to boot again afterward. Among the more common issues, in terms of complaints after a Windows 10 update, were Bluetooth and Wi-Fi connectivity related ones. But there were have also been users complaining that after a restart, all files from the C drive had been deleted.
Microsoft has stated that it has “not seen these issues reflected in telemetry, support data, or customer feedback channels,” but is aware of social media reports that mention Bluetooth, a stop error with a blue screen, and other related issues. “We continuously investigate all customer feedback and are closely monitoring this situation,” Microsoft said in the known issues section of the update notes. Microsoft asks that any users experiencing problems use the Windows + F keyboard shortcut, or select Feedback Hub from the Start menu, to provide feedback so it can investigate.
More practically speaking, if you are experiencing any Windows Update issues, I would always suggest you head for the Windows Update Troubleshooter. This, more often than not, fixes any error code problems, Be warned, though, I have known it take more than one running of the troubleshooter before updates are all successfully installed, so do persevere. That’s far better than not installing a security update or even uninstalling one if you ask me.
