What is the NHI event source and its event id 1 in the Microsoft windows system event log?

Many Dell Precision 7720 laptop users with Microsoft Windows 10, Version 20H2 face the following events showing up in the Windows System Event Viewer.

Let me paste the event,

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
  <System>
    <Provider Name="nhi" /> 
    <EventID Qualifiers="16384">1</EventID> 
    <Version>0</Version> 
    <Level>4</Level> 
    <Task>0</Task> 
    <Opcode>0</Opcode> 
    <Keywords>0x80000000000000</Keywords> 
    <TimeCreated SystemTime="2021-12-01T11:50:49.4168316Z" /> 
    <EventRecordID>143446</EventRecordID> 
    <Correlation /> 
    <Execution ProcessID="4" ThreadID="22492" /> 
    <Channel>System</Channel> 
    <Computer>Precision-7720</Computer> 
    <Security /> 
  </System>
  <EventData>
    <Data /> 
    <Binary>00000000010000000000000001000040000000000000000000000000000000000000000000000000</Binary> 
  </EventData>
</Event>

If you closely look at the event data, you can find the below findings

number one source of the event that is showing NHI
next is Event ID which is “1”, we will discuss it later What is NHI and What is Event ID 1

First of all, let me explain the event’s cause and its solution

This NHI (Native Host Interface) event is about the thunderbolt driver for your Dell laptop.

So, the First step is, that you need to make your system with the latest drivers and BIOS too.

After updating all the drivers and BIOS, your problem will definitely solve.

You can update or Download manually the latest driver for Dell Precision 7720

What is NHI(Native Host Interface)?

NHI is a Native Host Interface. I would suggest that it is related to the thunderbolt driver for your Dell. Make sure all your drivers are up to date and you are running the latest BIOS.
We can say it’s driver related issue Because in several devices we can find the same event id 1 and event source NHI which is Native Host Interface.
I think you got my point!

What is event Id 1?

In the above question, we have explained NHI in context with event id 1.
Same here we need to understand event id 1 in relation to NHI because many times you may find event id 1 with source is not NHI!

Let me elaborate,

Event ID is just a unique number for the “NHI” event source.

The vendor that publishes and logs these events makes up these numbers.

The inability to locate the description indicates that the DLL—which contains the template for these events—is either missing or has been registered improperly.

Hope this answers your questions. Do you have any doubts or findings on this?
