Windows 10 Code 43 on HD 4600 Display Adapter

[CMark]

After doing Windows 10 install, the Dispaly Adapter for the Intel HD 4600 reports a code 43 error and the adapter is disabled.  Uninstalling and reinstalling the driver (also tried win 10 driver from intel) does not help.  How do I fix?

I have the same problem. My display adapter is AMD Radeon TM 7450. I have try both AMD offical driver and Windows Update driver but it's no working. Code 43 made me so angry and corrupt my work. How can I fix it

Me too.

Tried Intel's driver updater, tred it in compatabilty mode; nothing works.

HP's update assistant tells me everything's up to date.

So now the laptop screen's the only thng avalable, and that makes me very unhappy.

Very unhappy.

Guys, relax, there's no solution.

I have the same problem with 6470M, I fought 3 days in a row, eventually downgrade to Windows 7

Also the same problem. I have an ENVY TouchSmart m7-j010dx. After installing Windows 10, my second monitor gives a black screen

• Display Settings in the control panel says I only have 1 monitor.
• In Device Manager, the Intel HD 4600 driver has a code 43 error.
• I have tried rebooting and updating the driver without success. (The intel Windows 10 driver for the 4600 refuses to install, saying it hasn’t been validated).

A fix will be greatly appreciated.

Just finished a chat/remote-assistance session with HP. 

Apparently there was/is an issue with the driver in Win8.1, and it's not resolved in W10. Upgrading to 10 just makes it apparent.

He says use the W8.1 recovery disk to roll back to W8.1; fix the driver issue (he'll send instructions for that); then re-install W10.

A drag, but at least an answer!

It'll take me a few days to go thru the process, and I'll post results here.

Stay tuned...

Definitely a drag.  Here's hoping it works...

I got it working!

When running under win 8.1 I had occassionally used a third monitor via a j5create usb to vga adapter.  After giving up on getting the hdmi to work under win 10, I plugged in the j5create adapter  to see if it would work.  After the automatic install of the j5create driver, voila, the intel HD 4600 driver started working; and it continued working after unplugging the j5create adapter.

Which j5create adaptor?
