Windows 11 KB5043145: Crashes and System Failures

Numerous users have reported being unable to boot their systems post-update, particularly affecting ASUS laptops—but the problem is not exclusive to them. Concerns have been echoed on platforms like the Windows 11 subreddit, where many shared their adverse experiences.

Microsoft has officially acknowledged these issues in their Release Health documentation, citing reports of frequent restarts, crashes leading to blue or green screens, and instances where computers land in an automatic repair mode following failed boot attempts. This situation is especially critical for PCs running Windows 11 version 23H2 and version 22H2, which are reported to struggle with these malfunctions.

Impact on USB Port Functionality

In addition to system crashes, users are experiencing issues with their USB ports and connected peripherals—like keyboards and mice. If your devices are malfunctioning since the update, KB5043145 could be the root cause. One user shared that uninstalling the update restored functionality, which suggests this may be a viable solution for others facing the same problems. Furthermore, some individuals have noted that their WSL2 environment ceased to operate following this update, signaling broader compatibility issues.

Advice on Managing Windows 11 Updates

As a precaution, remember that the KB5043145 update is classified as optional. It pertains to users who have selected the setting “Get the latest updates as soon as they’re available“under Settings > Windows Update. If you haven’t done so, it is wise to keep this option unchecked to avoid similar issues in the future.

Looking ahead, Microsoft is expected to roll out the Windows 11 24H2 feature update in October. While the allure of new features can be tempting, rushing to install them might leave your system vulnerable to bugs and stability issues—as demonstrated by the KB5043145 update.

On a related note, Intel has released a microcode update to address stability problems in its latest 13th and 14th generation processors, though users must wait for motherboard manufacturers to issue BIOS updates that integrate this microcode.
