Looks like we have another major issue with the newest kid on the block. The Windows 10 May 2020 Update was released just over a week ago, and is available on Windows Update.
Only for a select few.
The reason being that this release has a bunch of significant known issues for many users. These mostly stem from hardware configurations of the affected systems. But apparently, one issue that has not yet been documented has got to do with Intel Optane.
Intel Optane Memory is a high-performance piece of circuitry primarily used by enthusiasts.
And a number of these users are reporting issues, with reports scatted across the Intel forum, the Feedback Hub, as well as good old Twitter. It appears that Optane Memory Pinnings are not being migrated to the new update.
The result being Windows is essentially left trying to launch a program with .dlls that do not exist.
What’s interesting is that some of these reports date a couple of months back, meaning Insiders reported them to Microsoft during testing. The fact that they still exist is not surprising, as Redmond has had plenty of other issues to work out.
Anyway, the long and short of it is that Microsoft is not offering the May 2020 Update to those with Intel Optane Memory, even as this issue is not listed on the official known issues page.
If you are using Optane in your PC, you might want to hold off upgrading to this latest release.
At least, until the situation clears a little.
