I'd like to know how you are saving the screenshots you took. I have the screenshot efi driver. What F key to use and where is it saved ?...
With the CrScreenshotDxe driver pressing F10 when I am in the OC menu. I use Apple keyboard, it may be that on Windows keyboard it is another key.
If I run CFGLock.efi or VerifyMsr2.efi directly from the OC menu, CrScreenshotDxe doesn't capture those screens you see. I have to start OpenShell.efi and run each one of the tools entering the folder that contains them (eg FS2:>\EFI\OC\Tools\).
Screenshot is saved in the current folder where the OpenShell prompt is. When I take screenshot directly at OC menu, without entering OpenShell, it's saved at the root of the EFI partition.
Remember that after running CFGLock.efi you have to reboot to see the change with VerifyMsr2.efi.
