I can't load my file system mini-filter drivers on Windows Test Mode.

Question

Hi, everyone

I can't load my file system mini-filter drivers on Windows Test Mode.

driver is signed as EV Code Signing Certificates correctly.

test mode is set correctly and secure boot is disabled.

I can load test signed driver and MS signed driver.

Just EV Code Signing driver is problem only.

I've got the 0x80070241 error.

This error means that

"Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. "

yeah, we can see this error also on Windows normal mode when signing is problem.

But it is test mode. As I think, it should be loaded if driver is signed as whatever.

Plz let me know, if I don't know some policy of driver signing on Windows Test mode.

To sum up, on Windows Test Mode

1. EV Code Signed driver - Failed Loading
2. test signed driver - Succeed Loading
3. MS signed driver - Succeed Loading

Thanks in advance.
