Recently, a Windows 11 update has raised alarms by flagging a critical Lenovo tool as unsafe, leading to significant challenges for users attempting to install BIOS updates on their laptops. This decision stems from a change made by Microsoft in Windows 10 and 11, targeting the executable file WinFlash64.exe, which is necessary for BIOS updates on various Lenovo models.
Due to this modification, certain Lenovo laptops are now unable to install essential BIOS updates following the most recent Windows patch. The reasoning behind this change appears to be rooted in enhancing security protocols, but it has inadvertently caused frustration among Lenovo users.
However, before you consider drastic measures, there's a silver lining: a remedy is reportedly on the way. In the meantime, Lenovo ThinkPad users may utilize Windows Update to apply BIOS updates directly while bypassing the BIOS Update Utility, provided the relevant patch is available. Lenovo is also in the process of addressing the issue, with an expected fix included in the upcoming BIOS version (v1.61).
Although it is unusual for a BIOS update tool to be flagged as a security risk—especially considering the inherent risks associated with BIOS updates—let's remain optimistic that a swift resolution is on the horizon, allowing users to seamlessly update their systems once again.
