This Latest Windows Update Patches A Monstrous Amount Of Flaws
On August 08, 2025, Microsoft launched amassive patchwithWindows Update, which included fixes for everything from the .NET Framework all the way down to Windows PowerShell. Broken down, that’s 101 CVEs, 16 Knowledge Base articles, two zero-days, and 26 updates to Microsoft Edge. Even Microsoft Office Excel had its own share of fixes, including two remote code execution vulnerabilities —CVE-2022-24473andCVE-2022-26901.
The two most significant exploits that have been patched up in the sizable April update are called “zero-days,” which are basically just previously unknown vulnerabilities that may or may not have been actively targeted or exploited by a bad actor (rather, a hacker with malicious intent), but were exposed to the public on the same day that they were patched. In this case, one of the two addressed zero-days,CVE-2022-24521, had actually beenreported by the NSAfor having already been exploited by bad actors who could target Windows 10 systems, particularly enterprise server builds, and remotely take control of a vulnerable system by elevating access privileges through Microsoft’s Server Message Block protocol. Luckily, the latest update patched that issue, so it should no longer pose a threat to Windows users.
Within the aforementioned 26 updates toMicrosoft Edge, Microsoft also integrated over 17 fixes for Chromium, the open-source web browser engine used by Microsoft Edge and is actively developed by Google separately from its own Google Chrome web browser.
Microsoft continues to shore up against bad actors
Of course, Microsoft is currently on the case. Its Detection and Response Team (DART) has been working alongside theMicrosoft Threat Intelligence Center(MSTIC) since the threat originally became clear in March 2021. As of April 12, Microsoft has detailed itsrecommended best course of actionfor users who are looking to root Tarrask out of their own systems.
Until an official fix is issued, Windows users will have to make do with the manual security directives offered by Microsoft. However, this is just one ongoing issue, and it pales against the admittedly large collection of other fixes that were included in the April 2022 update. In all, the recent update addressed over 145 issues across many different Windows platforms, and it equates to a much more comprehensive patch than Microsoft’s previousMarch 2022 update, which only addressed 94 issues by comparison.
