This update addresses several critical issues, notably an enhancement to the Windows Subsystem for Linux (WSL2). A previous case sensitivity issue in GPU paravirtualization has been resolved, ensuring smoother operations for users running Linux applications on Windows.

Additionally, the update implements a revised driver list for the Windows Kernel Vulnerable Driver Blocklist. This aims at improving security by blocking drivers that may pose risks, reassuring users from the threats of “Bring Your Own Vulnerable” attacks.

However, a side effect of this security enhancement means that older applications managing hardware features like fan speeds may face disruptions as the update blocks their functionalities. Users who have relied on such legacy apps should explore updated alternatives post-installation.

Lastly, the May 2025 update eliminates recurring errors with SgrmBroker.exe in the Windows Event Viewer, a relief for many users who have encountered these errors after monthly updates.

It’s important to note that following this update, some Windows 10 systems might not show seconds in the calendar flyout, reflecting an ongoing shift in user interface design from Microsoft.
