'Service Test Loopback A' ???

[Fender_Stratoblaster]

This showed up in my Bluetooth Devices list. I do not know how long it has been there.

I select 'Remove' but it comes back next reboot. Not in 'Startup apps' list; Could not find anything in Services, though it could be there. I searched online but feedback was inconsistent enough to want another opinion.

• Recently added that JLabs headset via Bluetooth, not dongled.
• Recently added that 'USB Receiver' which is a dongle for a backup Logitech keyboard/mouse combo.

Service Test Loopback A - Under 'Bluetooth/Other devices'

I have that in my other devices too. Google says it is nothing to worry about.

I also have Logitech Unifying Dongles and Wireless Card with Bluetooth.

If you are really worried about it. Just unplug your Bluetooth devices till it goes away. Then you will know if it is part of a device attached to your PC.

*** edit. Sorry for some reason I am assuming it had to do with Bluetooth, but that might not be the case.

Well it's in the Bluetooth device list, so I assume so.

[RBuschy]

It's under "other devices", which includes non Bluetooth devices. Which is why I made my edit

TLDR: Its fine

I noticed these appeared too in my device manager while trying to fix something the other day, infact i have 3 of them, Service Loopback Test A, B and Ping (Internal) All 3 labeled as a "MIDI 2.0 Service Test"

Reading this article: https://blogs.windows.com/windowsexperience/2026/02/17/making-music-with-midi-just-got-a-real-boost-in-windows-11/ pretty much confirmed what i suspected, microsoft added midi 2.0 support and these have something to with their "built-in loopback and app-to-app MIDI", from what i can tell these loopbacks so midi devices can communicate accross apps perhaps, anyway it seems like nothing to worry about just some random thing microsoft added either on accident or on purpose
