100% Disk Usage on Windows 10: The "MessageSignaledInterruptProperties" is missing from the registry

This question relates to this article: https://support.microsoft.com/en-gb/help/3083595/task-manager-might-show-100-disk-utilization-on-windows-10-devices-wit 

I have this problem (100% disk usage on Windows 10) and have correctly followed all the steps to solve it. However, when I go to the registry editor and follow the path described, "MessageSignaledInterruptProperties" is missing and I am therefore unable to change the value. 

I have looked at the registry permissions and changed the necessary settings. I have extensively troubleshooted this issue and used all other available tools such as driver updates or this https://answers.microsoft.com/en-us/windows/forum/windows\_10-hardware/how-to-fix-100-disk-usage-in-windows-10/7c5c979b-0ed0-4855-b9b8-05b9499533e2

Any advice will be much appreciated - thanks in advance.

Sorry for the delays, Annika. As requested, please allow me to help you on this. Before we proceed, please read this note:

Note: The method to fix the issue will have Registry modification. Before you modify the Registry, make sure to back it up and understand how to restore the registry if a problem occurs. Please refer to this link: How to back up and restore the registry in Windows.

Here is what we need to do. On your end, you mentioned that you stopped at

***HKEY_LOCAL_MACHINE*System\CurrentControlSet\Enum\PCI\ <AHCI Controller>\Device Parameters*Interrupt Management*

From the PCI path of the Regedit, the steps are a little tricky. First, you need to locate your device's ACHI Controller. You can refer on this screenshot:

Which ever is missing in the registry, you should be able to add it. Here are the basic steps on how to add a registry key:

  1. Click the registry key under which you would like to add a new key.
  2. Click New on the Edit menu and then click Key.
  3. Type a name for the new key and then press ENTER.

Click and unfold the created key (MessageSignaledInterruptProperties), and right click on the right pane, choose New > DWORD 32bit Value > Name it MSISupported and change the Value data from 1 to 0, which is according to the article you've provided.

That is all. Please feel free to update us if this worked for you.

Have a great day,

Marc

    Dear Lizette,

    I haven't read Mar Cai's reply thoroughly - my mistake. The issue is solved, registry key added and edited (and disk usage back to normal from 100%!).

    Thank you, much appreciated.

    Kuba

    Hello Annika,

    As we checked, we've noticed that the thread, when it was originally created, did not have any reply from any of the community participators and volunteers. Therefore, we're here and would love to know if you were able to address the concern in such time. 

    Regarding the issue, we can say the steps you've tried will be able to meet the concern and can actually resolve it. However, you found out that the registry address that you were about to go to is not on your system. One workaround for this is to create the said path of the registry key, and see if it would work.

    Tell us more, when you need further assistance.

    Best regards.
