There is no windows 64. And, what driver do you think you need?
If you want assistance, you need to provide complete and accurate information.
Ok, but what driver do you think you need? There are dozens, if not hundreds of drivers.
What version of windows 10? 1909?
Did you upgrade from Windows 7 to Windows 10?
What do you think you are missing? WIndows 10 has all the drivers you need "inbox".
As I said, provide COMPLETE information.
I hope that you have an add-in graphics card and are not using the processor's graphics engine. The driver support for this is pretty bad, now that board and supported processors are all discontinued.
