Microsoft releases June 2020 Security Update for Windows 10: resolved 129 security holes, some very serious. How to update your PC
At least 129 security holes in Windows 10, and not only, have been resolved with the latest cumulative security update released by Microsoft, the June 2020 Security Update, identified with the code KB4560960. With that update, the operating system version moves to build 18363.900.
Many of these vulnerabilities, now fixed by Microsoft, were quite dangerous if exploited by hackers. Fortunately, however, at least at the moment there are no cases of exploitation of these flaws (so-called "exploits"). However, installing this update is essential because it is in fact the biggest security update in Microsoft's history: never have so many flaws been solved in a single update. Also because, and this should be noted, some of the vulnerabilities are quite old and affect pre-Chromium versions of Edge and even Internet Explorer.
Windows 10: Flaws fixed with June Update
The June Security Update fixes security issues related to Windows 10, Microsoft Edge (older EdgeHTML-based versions), Microsoft Edge in Internet Explorer compatibility mode (new Chromium-based versions), Microsoft ChakraCore JavaScript engine, Internet Explorer, Microsoft Office (including online), Windows Defender, Microsoft Dynamics (enterprise customer management apps), the Microsoft Visual Studio software development environment, Azure DevOps (a collaborative remote work toolkit), the HoloLens viewer, Adobe Flash Player, Windows App Store, Microsoft System Center (a systems administration software), and Microsoft's Android app (with which you can run Android apps on Windows 10).
Windows 10: How to install the June Security Update
The June Security Update is already available for download via Windows Update. On most systems it is downloaded automatically, unless there are other previous preparatory updates that need to be installed first and have been blocked or delayed by the user. Given the importance and the amount of vulnerabilities fixed with this security update, it is a good idea to open Windows Update and launch the update search. If there are others waiting, they should be installed, then you can download and install the cumulative update KB4560960. It may take several reboots of the operating system to complete the procedure.
