This is a problem that slipped past Microsoft, even as a large number of users did report this issue during development of Windows 10 version 2004. Luckily, this being a high-profile problem meant that all stakeholders were on it right away.
So high-profile that Intel has updated PCWorld on how the company has been in touch with Microsoft regarding this.
A solution for this problem is being worked on as of this writing, and should be out soon.
In the meantime, the chip giant has published a support document meant to help users troubleshoot this memory pinning issue on Windows 10 May 2020 Update. If you have encountered this problem, then you can follow these steps below to fix it.
- In Start Menu, type cpl to open Programs and Features.
- Look for Intel Optane Pinning Explorer Extensions in the list of programs.
- Right-click on it, and then select Repair.
- Once done, press Windows + X and select Device Manager.
- Expand the Software components field.
- Here, right-click on Intel Pinning Shell Extensions, and select Uninstall device.
- Check the Delete the driver software for this device, and click Uninstall.
This will repair and remove the old pinning package.
And should fix the “Unable to load DLL ‘iaStorAfsServiceApi.dll’ error.
Interestingly, Microsoft has still not yet listed this Optane problem as a known issue on its official page, but the May 2020 Update has been blocked on several devices with this Intel hardware. Meaning, the issue is rather widespread.
But the good thing is that Intel assures that the abovementioned steps will mitigate the problem.
