- Some owners of Lenovo Thinkpad cannot install BIOS updates due to a security setting that Microsoft applied in the last Windows patches
- This is happening to those who are installed through the update usefulness of Lenovo Bios or the Vantage application
- A solution is already intertwined and, as a solution, you can install through Windows Update
Some Lenovo laptops are seeing that BIOS updates do not work thanks to a change that Microsoft has just done in Windows 11 (and Windows 10).
The last Windows publication saw a Lenovo support publication that addresses the problem that affects those who try to apply an update to the BIOS with their ThinkPad notebooks.
Apparently, the problem is due to a Microsoft adjustment made to block a certain executable file (Winflash64.exe) in the last patches for Windows, a change made for security reasons.
When trying to apply an BIOS update using the Update of Lenovo BIOS update or the Lenovo Vantage application, some Thinkpad owners could see that the process fails, accompanied by some type of error message. There are some mistakes that may appear, but everything is equivalent to the same: the update did not work.
What is happening is that following the patch, and Microsoft updating its list of security blocks in it, the update is detected as a “vulnerable controller”, which means that it is a risk to the system, therefore, Windows refuses to execute the process.
As mentioned, the changes in the block list were made in the last patches for Windows 11 24h2, 23h2 and 22h2, together with Windows 10 22h2, all active versions of the Microsoft desktop operating system, in other words.
A solution is already incoming, or you can use Windows Update in its place
As Windows Last points out, Normally Lenovo recommends using its BIOS update usefulness to update the firmware of your laptop, since it is generally more reliable than other methods.
Obviously, given this new problem, that is not the case and, therefore, the easiest way to work on the failure is to use the Windows update to apply the BIOS update for its Lenovo ThinkPad. That is, assuming that Windows 11 (or 10) has found the relevant patch and has marked it in Windows Update. If not, all you can do is keep reviewing the updates and expect it to appear soon enough.
Meanwhile, Lenovo has been working on the remedy of this problem, and according to Windows Latter, he is in his place with the new version of the BIOS (V1.61) that is being implemented. Therefore, if you can make that last turn in the BIOS, it should work well by installing through the update usefulness of the Bios de Lenovo: the crossed fingers.
In any case, this should be a temporary hypo for the owners of Lenovo ThinkPad, but it is quite strange that an update of the BIOS will be marked as a risk like this in the first place. That said, of course, there is always a small level of risk involved in any update of the BIOS, such is the nature of the beast, and if you want to read more about the correct procedure to apply them, to ensure that you do well, we have an article dedicated to that.
