Windows Update KB5041585 Causes High CPU Usage and System Slowdowns

27 Aug 2024

KB5041585 will become an infamous example in the history of Windows updates. Despite the fact that the update implemented several improvements and fixes, it also causes problems.

Security Fixes and Critical Vulnerabilities

The release of KB5041585 aims to fix CVE-2024-38063, a critical vulnerability that could allow attackers to seize control of a system utilizing IPv6. This makes the update a crucial component for maintaining system security.

Another significant issue addressed by KB5041585 was the persistent Blue Screen of Death (BSOD) problem related to BitLocker. Users who entered the correct BitLocker key found themselves facing a BSOD instead of gaining access to their systems. Fortunately, this particular bug appears to have been resolved.

Still Problems

However, as is often the case with software updates, KB5041585 has introduced its own set of challenges. Reports indicate that users are experiencing unusually high CPU usage, resulting in elevated temperatures, increased power consumption, and a noticeable slowdown in system performance. The root cause of these issues remains unclear.

In some instances, systems are failing to install the update altogether, leaving the IPv6 vulnerability unaddressed. Microsoft is actively encouraging users to implement this update, and those who wish to ensure its installation can refer to a roadmap provided by Windows Latest for guidance.

What is the Update Guilty Of?

Determining the full extent of problems linked to KB5041585 has proven challenging. For instance, one user reported that their Wi-Fi connection either failed to connect to the Internet or experienced significant slowdowns. Even attempts to uninstall the update were thwarted, as it seemingly reinstalled itself without consent. Another user faced multiple BSOD incidents, highlighting the varied nature of the update’s impact.

A recurring theme among Windows users is that those who are not experiencing issues seldom report their experiences. This makes it difficult to gauge the true scale of the problems at hand. Nevertheless, the volume of complaints from dissatisfied users has noticeably increased, with many reporting serious concerns. Some applications are being incorrectly flagged for high memory usage through Windows’ dialog box, despite not being the actual culprits. This suggests a potential flaw in Windows’ resource management, leading to misleading notifications and further confusion among users.
