Swap still reported even though Page file is disabled

I originally asked this question a while back:

Can't avoid swapping on Windows cluster

We have a cluster that has three indexes (one main, and two supporting) with 5 shards and one replica. I am using 7 Windows nodes, each of which have 8 cores and 56gb RAM. I have set the heap to use 28gb. I have disabled the paging file in the OS and set mlock to true. No matter what I have tried, I am still seeing swap being used. ElasticHQ is reporting between 19 - 32 mb swap being used on the nodes. We have found that we have far exceeded the recommended shard size of 30 - 50gb. Our sh…

I was never able to get around it. I just set up a new cluster with significantly more resources in the hopes of improving our perf. I still find that there is a ton of swapping going on.

I am on Windows (so I can't use Linux methods for preventing swapping). I have completely disabled paging and rebooted. After going this, I get:

PS C:\Windows\system32> Get-Counter -Counter "\Paging File(*)\% Usage"
Get-Counter : The specified instance is not present.
PS C:\Windows\system32> (gwmi Win32_ComputerSystem).AutomaticManagedPagefile
False
gwmi win32_pagefilesetting

Windows is showing that there is no swap, but I still see:

        "swap": {
           "total_in_bytes": 60129071104,
           "free_in_bytes": 26670817280,
           "used_in_bytes": 33458253824
        }

I can't seem to get around this. Here is what VMMap is showing

Has anyone been able to disable swapping on Windows?
