The latest Windows Server 2022 update KB5015879 (OS Build 20348.859) is here with multiple improvements and bug fixes including performance boost in IOPS, a fix for a Defender bug, and more.
A new report suggests that Microsoft Defender has a bug which is causing it to hog the CPU resources on a system using an Intel processor, leading to reduced performance. AMD is apparently unaffected.
Windows 11 has several new security-related features. One of these features called Smart App Control that intelligently blocks suspicious apps and files blocked one of Microsoft's own files.
Microsoft Defender for Endpoint is apparently causing several issues for clients on Windows 10 20H2 systems. These issues include very high memory usage bug, black screen on boot up, and more.
Microsoft's Defender for Endpoint security solution had yet another false positive incident today as it appears to have wrongly flagged recent Google Chrome updates as "suspicious".
SmartScreen on Defender is apparently causing delayed playback issues in videos on the latest Beta Channel build 22581 for Windows 11 Insiders. For now, there is a simple workaround for the bug.
Microsoft's Defender for Endpoint security solution was detecting the company's own Office process as malware. The firm has since confirmed that this was a false positive with nothing to worry about.
A Microsoft Defender bug is creating thousands of files and clogging the boot drive on Windows Server 2016 and 2019, according to user reports. It is now being fixed via an update to the service.
