Ran into it an hour ago also.

I did check as stated in the above link, but was already disabled.

Restarted, seems to be fixed for now.

Otherwise I will uninstall Intel Radip Technology software entirely...

Nope, it came back.

I uninstalled the Intel Optane Pinning Explorer Extensions

How did you do that

Welcome to the Dell Community  @Ebin2310 

Go to the “Control Panel”

Click on “Default Programs”

In the lower left hand corner click on “Programs and Features”

You could try to "Repair" first, if not then “Uninstall” any "Intel Optane Software" that may be installed.

Reboot.

You needn't uninstall anything.

I looked for where the iaStorAfsServiceApi.dll was supposed to live,C:\Program Files\Intel\OptaneShellExtensions, but I didn't have it that dll.

The Solution that worked for me is:

Under Add/remove programs select "Intel Optane Memory and Storage Management" from the right pane ("Apps & Features"). Select "Advanced Options", then click "Repair" and then "Reset"

Restart your computer and then that iaStorAfsServiceApi.dll will be present, and you will no longer receive the error.

my solution (Dell XPS 9570):

• download the actual version (17.5.1.1021) of Intel Rapid Storage Technology (SetupRST.exe)
• install the update and restart your Dell
• Have fun 

I did a Windows 10 update the other day. And since then I get the Intel Optane Pinning error.

I found the program in my control panel's Uninstall or Change a Program section, but it doesn't have a repair option. Only remove. What now?

Uninstall then reboot.
