THE Microsoft released a mandatory update for the Windows 10 which is causing headaches for several users: it causes a critical error in the Start menu, prevents the Edge browser from opening, and causes the blue screen of death (BSOD) to appear on some PCs. The company says these problems should be resolved by an update in late October.
The flaws are related to update KB4517389, released on October 8. After installing it, some PCs display a critical error warning immediately after clicking on the Start button: “Your Start menu is not working; we will try to fix it the next time you log in ”.
About the bug in the Start menu, a Microsoft employee says in the official forum: “We are aware of this problem and we estimate that a solution will be launched in late October”.
This may be related to security fixes in Windows Shell that are present in this update. Since the May 2019 Update, the Start menu runs in its own process (Start Menu Experience Host), separate from the rest of the interface (Shell Experience Host). The idea was to avoid gagging and make it open faster.
And, as noted by Bleeping Computer, some users are no longer able to open Microsoft Edge by clicking the icon: the browser only opens when you click a link, if it is set as the default. This will also be resolved at the end of octobersays Microsoft.
Windows 10 has blue screen problem after update
There is another more serious problem: the PC may display the blue screen of death (BSOD) after installing the mandatory update. “My laptop was working fine until I installed the last two updates, now it doesn’t want to boot and, when it starts, it runs very slowly”, explains a user in the Microsoft Answers forum. The failure was resolved after uninstalling KB4517389.
Two other reports on the Microsoft forum also mention the BSOD after installing this update. In both cases, a technical advisor found that it was a flaw in Intel’s Wi-Fi driver.
Even after removing the Intel driver and installing the latest version offered by the manufacturer (not Windows), the problem persisted – this time because of an Nvidia driver. The recommendation was also to uninstall the problematic update.
