I just recently learned about Windows Platform Binary Table or WPBT, which allows motherboard manufacturers to bundle software with their motherboards that will be automatically installed by Windows. And while it was ostensibly meant to be used to bundle important drivers, it can and has been used to bundle bloatware or other software with exploitable security flaws.
When I install Windows, it's important to me to have it be as clean as possible, which means no third party software or configurations of any kind, so I can start from a totally fresh, unsullied state when configuring it. So naturally I want to disable WPBT (which luckily appears to be possible on certain motherboards) and prevent anything else like it from tampering with a system.
Are there any other features on modern motherboards that could prevent a new Windows installation from being totally clean?
I'm looking for anything that could be used to bundle drivers or software, or store software, settings, profiles, or other data from a previous Windows installation (for example Wi-Fi networks and passwords, vendor branding, security updates, etc.) in such a way that it would survive completely wiping any drives connected to the motherboard.
