incompatible driver igdkmd64.sys

[DMH681]

Edition Windows 10 Home Windows 10 May 2021 Update (21H1) I'm trying to turn on  Core Isolation and I'm getting a message that says  igdkmd64.sys Incompatible and will not turn on.  Is there an update to this and where is it?

Sadly, no surprise. These SCUM (HP and Dell both) are relentless. They run their support groups for profit. Imagine!

Dell is actually the worst. Their scam is to have you run this so-called exhaustive hardware test. Then, when (not if) the test finds nothing wrong, they say that it isn't their fault and them investigating any further will cost you money. Yea, right. Their test facility is a scam facilitator and nothing but.

You pay good money for support in your original expenditure and they still want to charge you additional money to actually give you support. If they can't get any additional money out of you, they blame it on Intel and dump you off here. Of course, if this is a system-level or laptop product, you don't even have a warranty from Intel. The processor, the chipset, the LAN and WLAN components, etc. are all covered by the warranty from the vendor, not Intel. Your warranty is exclusively from the vendor. Still, when they dump you here, Intel helps you out to the extend that they can, usually no questions asked (they do draw the line at discontinued products, however). Think about this though: when they sluff you off to Intel with your problem, you are represented by one voice. If HP or Dell come to Intel with a problem, on the other hand, they are representing many thousands of voices. Who's issue do you think gets priority? Not yours, that's for sure! Numbers talk. Bottom line, when the sluff you off, they are actually lowering the priority of your issue significantly!

People complain about Intel support. AFAIAC, Intel has the best support in the business (unfortunately, considering companies like HP and Dell, that isn't saying much). Most people who are complaining about Intel support are complaining because their problem is not fixed instantly. They have no concept of proper software development processes. They have no grasp of the time that is actually required for the full validation of a release. If their problem is one that is truly caused by a software/driver/firmware bug, then it is going to take literally months to be addressed. This is reality.

Off my soapbox now...

Yeah, and not only did they want to charge me, but they wanted me to give them full access to remotely take over my pc so they could remotely check/fix any problems it has...   Are ya seriously believing I'm going to hand over my pc... hahahahahaha.. oh yeah, I forgot, I was born yesterday...

I know it's been a couple of years since this was posted but I just recently switched to UEFI.  I ran into exactly the same problem with the same driver while trying to turn on Core Isolation.  I Asked the obvious question on HP Support.  They responded with 100 references, NONE of which addressed the issue.  Apparently they still don't want to be bothered with helping us solve the problem.  I've been all over the internet looking for a way to fix this thing.  Even on the Microsoft site.  Looks like I just won't be turning on Core Isolation.  Makes me wonder why it's even there.  I'm inclined to jump on the "soap box".  I know each one of us is only one out of millions, but also, each of us spend money with these outfits amounting to a great deal in the end.  Seems like they would like to accommodate us just a little tiny bit.  Errrrrrrrgh!!!!!  Thank you, Intel, for the info.  RLC

I know this is an older post now, but I can across the same issue unable to enable core isolation because of driver igdkmd64.sys.  I used DDU (display drive uninstaller) to purge all display driver files. Once that completed I was able to enable core isolation, perform a restart and re-install UHD 530 drivers and everything is as expected now.  Hopefully this will help someone else searching.

Mr2toyou--Just wanted to say thanks for that response.  Like others, I was frustrated with that issue.  I have a new computer I just got (for Windows 11) and it doesn't have that problem but I'm going to pass the information on with whoever takes my old computer (it's still usable), just in case. 😌  RLCarson

I know this topic might be a bit outdated,

but since I was sent here by the almighty algorithm

- and I've had this problem several times after recent Windows 11 updates -

I thought I might be able to assist.

There are ways to remove problematic drivers.

Be careful — there is some risk involved, and you could potentially damage your system.

If you have an OEM###.inf file reference:

You can remove the problematic driver using this command (in a terminal with administrator rights, e.g., PowerShell or Command Prompt):

pnputil /delete-driver oem###.inf

Replace ### with the actual number from your system.

If needed, there's also a forced version

If you do not have an OEM file ID:

You’ll need to find the actual driver file name, then rename or delete it manually.

Some driver file examples I’ve dealt with:

C:\Windows\SysWOW64\Drivers\HWiNFO64A.SYS

C:\Windows\System32\drivers\S332x64.sys

C:\Windows\System32\drivers\igdkmd64.sys

The last file (igdkmd64.sys) was the one causing problems for me.

I’m currently still in the process of getting rid of the yellow warning icon on the Intel HD Graphics 4600.

Even after renaming the driver, I still had to:

• Remove the graphics card device from Device Manager

• Restart the system

• Let Windows reinitialize the device

After that, the system worked — but with the default Intel graphics driver, the onboard graphics card went into problem mode.

Apparently, Intel has forgotten they ever made the Intel HD Graphics 4600. 😅

To be fair, this system wasn’t originally meant to run Windows 11 — so some compatibility issues are to be expected.

So the real question is:
Do you prefer keeping kernel isolation enabled, even if it causes driver conflicts - or would you rather disable it to have a clean Device Manager without warnings or issues?

Best regards

The short answer is that there is no solution to this problem.

igdkmd64.sys hasn't been updated since 2016, and it won't be getting any more updates because it's for a very old discontinued product.   

If you want to take advantage of Core Isolation, you're going to need a newer computer.

The final version of this driver is 20.19.15.4531 (Released 29 September 2016).

"If you want to take advantage of Core Isolation, you're going to need a newer computer"

Correction: you _may_ need a newer computer

More accurately: you will need to replace the hardware that is raising this error message. In the current case (and I have no idea what type of computer we are talking about here, desktop or notebook) it might be just a case of swapping out the graphics adaptor (or adding one, if it's built in).

😉
Use cases might differ.

In my case, I had several all-in-one PCs like the Dell OptiPlex 9030 AIO,
which come with some pretty ancient Intel graphics cards — like the Intel® HD Graphics 4600.

Removing the driver and rebooting allowed me to activate kernel protection!

However, since then, I’ve had an “error message” in the device manager.
Still, the system does display a picture — using the Windows Basic Display Driver.

There might be systems that go completely dark after a reboot.
So far, I haven’t encountered any - but, like always, you really should know what you're doing.
Especially if you need the original graphics driver,

know how to access the system remotely, or how to boot into some “fun” recovery mode. 😉

So yes — it does work.
But...

If you want a clean device manager, and if your system allows it,
you might want to replace the graphics card with a newer one
and disable the historical Intel onboard GPU.
Unfortunately, I’m out of luck here — stuck with an all-in-one system.

Also worth keeping in mind:
it seems these drivers haven’t been updated in ~9 years.
And while I don’t think the cards are officially abandoned,
I wouldn't count on Intel fixing anything soon - or ever.

These systems might still run Windows 11 -  maybe via a server install or some exotic workaround -
but they’re always one Windows patch away from becoming decorative bricks. 😅

Intel graphics are pretty much always going to be the on-board ones, so swap out is not going to be an option.  Some motherboards allow the on-board graphics to be disabled, which might allow you to remove the driver.
