Driver cpuz143_x64.sys won't load when Speccy Pro runs in Win 11. Why? What's it needed for?
This is the driver that Speccy uses to examine your computer for its hardware and software and, thus, is quite required for the software to be able to function.
I would recommend uninstalling the software completely, restarting the computer via the Start menu, and then installing and registering once more. If this does not take care of the issue, please contact our support team via the Contact Us form located here: https://support.piriform.com/hc/en-us/requests/new?ticket_form_id=86507 or by emailing support@ccleaner.com directly and we'll be happy to look into this matter further.
