Hi, I'm trying to modify vmchipset.dll and make it use a modified Hyper-V UEFI firmware. (VMFW resource 13505, Host is Windows 10 Enterprise LTSC) When I make the modification and place it in \Windows\System32, whenever I go to start any virtual machine I end up getting a couldn't verify digital signature error (HRESULT 0x80070241). the vmwp refuses to start. from initial debugging it looks like it's an assert of sorts. Anyone know what's going on and if there's any way to bypass the signature check?
Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization, add reg value "RelaxWorkerSigning" with type REG_DWORD, content 1, and then goto "Image File Execution Options"(Google it), delete the vmwp.exe and vmcompute.exe. Then everything's done
