I can help!
That SMBIOS.reflechHost="TRUE" is for the BIOS...
Changing the results for dxdiag is easy but the display adapter GOES BACK TO VMware/VBOX after every reboot.
NO PROBLEM! Just export the section in regedit to a .reg file, hide it somewhere on your VM obviously not on the desktop lol... and just make it an additional step you have to do when restarting it, if you don't work with snapshots.
Go into regedit and search for whatever SVGA adapter your dxdiag is showing.
The "Chip Type" which is what changes each time. Name and Manufacturer are in that same section as DriverDesc and ProviderName keys. Note that I have circled the "Main Driver:" dll's too because they all say vm3d so I changed them to nv3d* because scammers looking in your dxdiag aren't stupid, or at the least, thorough.
Once you find, edit and export this section to a .reg file, all you have to do is run that .reg file for a quick replace. You could make it load on startup, but I wouldn't want the scammers to see that entry. Hope this helps?
