Why exactly is the Device Association Service needed?

So why does it take up so much resources when it's running? Pairing a device seems like a one time thing to do, why is always running?

Okay, so I found out that the only thing that seems to work is to uninstall the Device Association Root Enumerator in Device Manager. As per this document: https://answers.microsoft.com/en-us/windows/forum/all/disabling-microsoft-device-association-root/b9d320df-c56e-4fbe-951f-4d09ed38da9a

Hello!

If it is using too many resources, this could be caused by a number of things.

First, unplug all the peripherals you can. If the issue goes away, plug them back in and test. This could resolve it by resetting that driver, but if not then that peripheral or its driver is a likely culprit.

Next, I recommend running the System File Checker.

1. Click Start and type "cmd'. Open Command Prompt as Admin.
2. Enter the following lines one at a time. Note any messages given, especially ones which state that something could not be updated or repaired. dism.exe /online /cleanup-image /restorehealth sfc /scannow chkdsk /R /F /X
3. Reboot

Test to see if the issue is resolved.

If this does not resolve the issue then this might indicate a problem with a device driver. Unfortunately, it can be difficult to determine which one.

1. Choose Start and type "device". Open the Device Manager.
2. Go down the list and look through each one. Check out peripherals and especially Bluetooth devices. If you find any symbols, such as a caution sign, that is your likely culprit.
3. If you find nothing, uninstall the Bluetooth drivers by right clicking on them and choosing "Uninstall device". You can do this with several devices at once, though you might disable your mouse or keyboard in the process.
4. Once you are done or have uninstalled your mouse or keyboard, reboot and test. If there are still devices you have not tried, repeat with them.

Lastly, if you find any device that you think is the issue but cannot resolve the issue, I recommend checking with the manufacturer to get the latest drivers installed.

With luck this should resolve the issue.

Hello!

My name is David N., and I am a Community Independent Advisor and Windows fan. I will be happy to assist you with your issue.

Device Association Service is used to enable pairing between devices. For example, if you wish to pair Bluetooth headphones to your computer you must have this service running. Other devices, including some devices that are plugged in directly, may also use this service.

If you do not have any devices that require pairing then you should be able to disable this service without loss of functionality. You will need to test thoroughly, as it might be required by unexpected devices such as a WiFi printer. Additionally, it will prevent pairing devices in the future, particularly Bluetooth devices.

I hope this helps! Please let me know if this resolves your issue or if you require additional assistance.
