Intel confirmed on Friday that there are issues with the Windows 10 May 2020 Update and Optane Memory after users began reporting compatibility issues last week. The specific issue was identified by Twitter user Krishna K, who shared an error message showing that Optane Memory cannot load the iaStorAfsServiceApi.dll. The Microsoft Education Twitter account confirmed that the user was correct in a follow-up tweet.
Thanks for bringing this to our attention. It seems that the Intel Optane isn't compatible with the recent update. Have you tried updating its recent driver from Intel by any chance?

An Intel spokesperson told PCWorld on Friday that the issue applies specifically to the company's Optane Memory H10 and Optane Memory M10 and that they were aware of the issue. Intel also published a support document that details steps users need to take in the event that they run into an issue with the impacted Optane Memory. The steps provided in the document outline how to repair Intel Optane's Pinning Explorer Extensions and removing the older extensions package.
While no definite timelines have been provided from Microsoft and Intel on a fix for the issue, Intel said that it's working with Microsoft to prepare a response including outlining further steps for users to get assistance with the issue. Microsoft's Windows 10 May 2020 Update already has several upgrade blocks in place and the Windows 10 Health Dashboard currently indicates no less than 11 known issues for the May 2020 Update. However, the known issues do not currently indicate any compatibility issues with Intel's Optane Memory.
For users who have any potential issues with the update, you will a message from Microsoft indicating that "your device isn't quite ready for it yet." Likely, it's a good idea to wait for Microsoft to push the update to your device automatically when it is ready versus trying to find some other update method.
