Windows 11 update flags a core Lenovo tool as risky – and it’s causing problems

Lenovo ThinkPad users are currently facing challenges with BIOS updates following a recent Windows 11 update. This situation has arisen due to a modification implemented by Microsoft, which affects both Windows 11 and Windows 10. The alteration specifically targets the executable file WinFlash64.exe, leading to complications for some Lenovo laptops attempting to install BIOS updates.

The latest patches for Windows, identified as 24H2, 23H2, and 22H2 for Windows 11, along with Windows 10’s 22H2, have introduced this change primarily for security reasons. However, the unintended consequence is that many ThinkPad owners are encountering difficulties when using either Lenovo’s BIOS Update Utility or the Lenovo Vantage app. Users report that the BIOS update process fails, often accompanied by various error messages, yet the outcome remains the same: the update does not proceed.

In fact, the operating system now categorizes the BIOS update for these Lenovo devices as a ‘vulnerable driver,’ which poses a risk to the entire system. Consequently, Windows prevents the installation from taking place altogether.

Potential Solutions on the Horizon

Despite the frustration this may cause, there is a silver lining. A fix is reportedly in the works. For the time being, users can attempt to apply the BIOS update through Windows Update, bypassing the BIOS Update Utility, provided that Windows has identified the relevant patch. If it hasn’t, users are advised to keep checking for updates.

Lenovo is actively addressing the issue, and with the upcoming BIOS version (v1.61), a resolution is anticipated. While it is somewhat unusual for a BIOS update to be flagged as a risk—given that a small risk is inherent in any BIOS installation—the hope is that this matter will be resolved swiftly, minimizing inconvenience for users.
