Unable to find how to update the Network speed in Windows

I want to understand where the value of Network speed is found in Windows and the options to change it.

I am using the Windows Sysinternals bginfo, which generates desktop backgrounds that include important information about the system. https://learn.microsoft.com/en-us/sysinternals/downloads/bginfo

It shows me that the Network Speed is 4GB.

I do not doubt that it is correct. I have see the performance during busy times and it never goes over 3.4GB.

The closest thing I can think of is Link speed

Get-NetAdapter is showing that the NIC speed is set to 10Gbps.

PS C:\Users\xxxxx> Get-NetAdapter

Get-NetAdapterHardwareInfo shows the speed in GT/s, which is Gigatransfers per second.  1 GT/s is 8 times bigger than a GB/s

There are no QoS rules set on the Windows machine.

Running Get-NetQosPolicy showed nothing.

It is a virtual machine, Esxi 7.0U3, on a VMware environment. The underlying vmnics look fine.

There do not appear to be any setting caps:
