[Solved] Why is my Win7 machine querying "none" 2x per second?

General

In my pihole log at /var/log/pihole.log, I'm seeing repeated DNS queries for none. Does anyone know what this is? Is something on my Windows 7 machine really making this request twice per second, or is this some sort of misrepresentation by pihole? I'm very new to pihole, so I'm still trying to understand everything. Hoping someone has had a similar experience and can shed some light on what is going on here. Thanks

Log snippet below - 192.168.2.188 is a Windows 7 workstation:

It is your Windows machine making the requests.
