With October 2020 Patch Tuesday cumulative updates, Microsoft made a change that aims to tighten Windows verification of driver software. This change has been introduced to prevent malware from exploiting vulnerable hardware drivers to compromise a Windows 10 machine.

As part of these new security improvements, Microsoft says Windows 10 will block users from applying OEM or manufacturer drivers if Windows can’t verify software publisher.

This change could lead to driver errors on Windows 10 if Microsoft is unable to verify the drivers.

Main goal here is money and ability to destroy small hardware vendors (if Microsoft will be requested to do such by authorities).
