Hi , i have install openxt 9.0.2 on a lenovo m920q and i have install a windows 10 21h2 vm

i have read w10 load only signed driver , so i have done this:

bcdedit /set testsigning on

installed the driver that comes with that release by mounting the virtual cd rom

reboot

everthing is ok except there will be forever a watermark on the lower right corner that say test mode.

i have also read that is not good to use windows 10 allways in test mode so i do bcdedit /set testsigning off and reboot , that watermark goes away but all openxt driver are not loaded anymore

i also tried to do this:

bcdedit /set testsigning on

certutil -addstore -f "Root" developer.cer
certutil -addstore -f "TrustedPublisher" developer.cer

developer.cer was downloaded from https://openxt.ainfosec.com/OpenXT/certificates/windows/

but again when i do bcdedit /set testsigning off and reboot i get the same problem
