Microsoft Warns Workaround Preventing Lenovo ThinkPad BSOD Increases Risk

An anonymous reader quotes ZDNet: Microsoft has finally published a support document detailing its workaround for the August 2020 Patch Tuesday update for Windows 10 version 2004 that caused blue screens of deaths (BSODs) on newer Lenovo ThinkPads and broke Windows Hello biometric login… It’s the same as Lenovo’s earlier workaround but comes with a stern security warning from Microsoft.

Microsoft also explains how Lenovo Vantage violates Microsoft’s security controls in Windows.

Users might bypass the BSOD screen, but they are endangering their computers by implementing the workaround, according to Microsoft. The workaround also affects some of Microsoft’s latest security features for Windows 10, such as Hypervisor Code Integrity for shielding the OS from malicious drivers, as well as Windows Defender Credential Guard. “This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk,” Microsoft states….

The good news for affected ThinkPad users is that Microsoft and Lenovo are working together on a fix. However, Microsoft hasn’t said when that will be available.
