Once the correct driver package (typically named CH9200_DRIVER_EXE or a compressed folder) is downloaded, the installation process on Windows 11 demands extra attention due to the operating system’s enhanced security features. Specifically, the CH9200 driver is not digitally signed with a certificate that Windows 11 fully trusts by default. To bypass this, users must temporarily disable (a Core Isolation feature) or restart the PC into "Disable Driver Signature Enforcement" mode. After extracting the downloaded files, the user should open Device Manager, right-click the unidentified device, select "Update driver," and choose "Browse my computer for drivers." Navigating to the folder containing the extracted CH9200 .inf file and clicking "Install" will finalize the process, often requiring a system reboot.
