Windows Defender False Positive Takes Down Open-Source Hardware Monitoring Tools

A recent Windows Defender update mistakenly flagged WinRing0, a kernel-level software used by many open-source hardware monitoring applications (like Fan Control and OpenRGB), as malware. This caused widespread disruption, with users experiencing unexpected behavior like high-speed fan activity. While Microsoft's move aims to enhance security, it's created a significant challenge for small, open-source projects. Updating WinRing0 requires a Microsoft digital signature, a costly process for these developers. Some companies are working on solutions, but many developers are facing difficulties, raising concerns about the future of these essential open-source tools.
