About

I created this program as a sort of "swiss army knife" of driver testing tasks. It can detect various situations where driver signing requirements by the kernel are altered, like in-place upgrades from an older Windows edition, Test-Signing status and the lesser known (now no longer working) "WHQL Test Mode" 😉

The secret WHQL Test Mode (which allows you to run cross-signed kernel driver binaries) might still be in the Windows kernel to this day, but cross-signing - a mandatory requirement - is now dead for a couple years, so it's no longer an option anyway.
