In WPF application, when execute windows workflow and take file open dialog continuously, handle leak is observed and workflow execution failed after some time due to high handle usage (>3500).

 

When disable windows explorer shell extension of Intel Optane memory, and execute the same scenario above, handle leak is not observed.

 

Installed version of Intel Optane Pinning Explorer Extension is 17.2.6.1027

 

Other users also reported similar problem (example, high CPU usage) and informed that issue gets resolved if uninstall Optane memory Pinning explorer extension. (https://answers.microsoft.com/en-us/windows/forum/all/high-cpu-memory-usage-from-explorerexe/5377ed1b-e4f3-4c9c-9e0d-6cacdf07f52c)

Hello, User15804729025686725761.

 

Thank you for contacting the Intel Community Support.

 

I checked the information regarding this error and the link provided, I will be glad to assist you.

 

Thank you very much for taking the time to report this, I can certainly submit your feedback.

 

Looks like this could be related to an error with a previous update, with the solution being the same; removing the extension. You may also check if there is a different version directly from your system manufacturer's website.

 

If there is anything else and I can be of assistance, please let me know.

 

Best regards,

Hi Bruce,

Thanks for your reply.

 

Updating Intel Optane Pinning Explorer extension to latest version (17.8.x.xxxx) will fix the issue? or just uninstall it?

 

Regards,

Vineeth

Hello, User15804729025686725761.

 

Something else to consider is that if you do not have an Intel Optane Memory installed in your system there is no particular reason for you to have this extension, it can be removed.

 

If you do have an Intel Optane Memory installed, try the following:

 

First, refresh the current driver package installed by repairing the Intel® Optane™ memory pinning extensions:

  1. Open Programs and Features (Press Windows key  + r).
  2. Type ‘appwiz.cpl’ and click OK.
  3. Locate and highlight Intel Optane Pinning Explorer Extensions.
  4. ClickRepair.

Second:

  1. Open Device Manager (Press Windows key  + x).
  2. 000055631-img5.png
  3. Expand the Software components field.
  4. Right-click the Intel® Pinning Shell Extensions field and select Uninstall Device.

Hi Bruce,

 

Is there a workaround to solve the issue other than updating Intel Optane Pinning Explorer Extensions?

Anything to do with .NET side?

Vineeth

Hello, User15804729025686725761.

 

There are no additional steps or workaround.

 

Keep in mind that if you don't have an Optane™ Memory in your system, you can remove any Optane™ associated tools like the pinning extension.

 

On the other hand, if you work with an Intel Optane™ Memory, you can disable Optane™ Memory acceleration, uninstall all the Optane™ related tools and then set it up again, depending on your system, using Intel RST, Optane™ Interface or Intel® Optane™ Memory and Storage Management.

 

Best regards,

Hello Bruce,

 

As you suggested, I uninstalled Intel Optane Pinning Explorer Extensions (including its drivers) using Device Manager.

But, when I restart the PC, it again appears under Software Components in Device Manager.

 

When checked Windows Event Viewer, I found a log that WindowsUpdateAgent installs it again and the log says "Successfully installed Intel Software Component - v1x.x.xxxx"

 

Then again, I uninstalled Intel Optane Pinning Explorer Extensions, but this time, before restarting the PC, I manually stopped Windows Update service and set its Startup type as "Disabled". Now, after restart, Intel Optane Pinning Explorer Extensions does not appear.

 

Since, Windows Update is required to be enabled on the PC, could you please suggest another way to prevent automatic install of Intel Optane Pinning Explorer Extensions during PC restart?
