Windows 10, by default, enforces strict security measures to prevent the installation of unsigned or poorly signed drivers, which could potentially be malware. Many niche electronics, particularly those from smaller manufacturers or generic development boards, utilize drivers that are not digitally signed by Microsoft. Consequently, users may find that the driver installation fails or the device still fails to start (Error Code 10 or Code 52).
