Whay is Microsoft Bluetooth Enumerator

Bluetooth has been a wireless connection standard for ages and it’s been tremendously upgraded throughout the years. Oddly enough, cross-device incompatibilities still plague the popular Bluetooth. The incompatibilities result in slow connection and bad device-to-device communication.

Whay is Microsoft Bluetooth Enumerator

Microsoft Bluetooth Enumerator is a protocol set, essentially a set of guidelines, used to organize and facilitate the transfer of data between Bluetooth devices. If you aren’t familiar with the ‘enumerator’ term, these devices are usually referred to as Bluetooth adapters, or more commonly, dongles.

How It Works

In essence, a Microsoft Bluetooth Enumerator (dongle) is a wireless adapter that makes it possible for a PC without integrated Bluetooth to establish a connection with a Bluetooth device, like Bluetooth keyboards, mobile phones, and mice. This type of dongle helps the PC communicate with devices that it wouldn’t be able to communicate with otherwise.

In more technical terms, a Bluetooth Enumerator functions through its integrated Bluetooth radio that sends electronic signals in binary code.

Disable the Microsoft Bluetooth Enumerator

If you don’t need the dongle, you simply don’t have to use it. It’s when it starts interfering with other Bluetooth devices, that it becomes a problem. The solution here is rather simple: disable the device until you need it. Here’s how to disable the Microsoft Bluetooth Enumerator:
Disable the Microsoft Bluetooth Enumerator

  1. Go to Start.
  2. Find, or type in “Control Panel” in the search box.
  3. Open Control Panel.
  4. Find the Hardware and Sound icon and click it.
  5. Find the Device Manager and click it.
  6. Find the Bluetooth node on the list and double-click it.
  7. Right-click the Microsoft Bluetooth Enumerator.
  8. Select Properties.
  9. Click the Driver
  10. Click the Disable
  11. Confirm by clicking Yes.

Microsoft Bluetooth Enumerator should be disabled now and shouldn’t interfere with other Bluetooth devices any longer.

Reinstalling the Microsoft Bluetooth Enumerator

As is the case with any device, Bluetooth dongles too tend to break or start behaving weirdly. If it happens with your Enumerator, the best thing to do is to reinstall it. The process of deleting the feature is fairly straightforward. Reinstalling will take some time and dedication, however.

Uninstall It

  1. Follow the steps from the previous guide up until step number 6.
  2. Left-click the Microsoft Bluetooth Enumerator.
    Uninstall It
  3. Find and click the “X” button in the upper menu of the window.
  4. Confirm by clicking Uninstall. This will uninstall the driver.

Now that you’ve successfully uninstalled the Microsoft Bluetooth Enumerator, you’re going to have to install it from scratch. This might take a bit of work that you might not be used to.


There are 3 methods that you can use to reinstall the Bluetooth Enumerator.

Method 1: Rename the Bth.inf file

In order to install or reinstall any third-party stack or device, you’re going to have to rename the corresponding .inf file. hTe one we need here is %WINDIR%infBth.inf. Here’s how to do it:

  1. Click Start.
  2. Type in “Run” in the search box and hit Enter.
  3. In the Run menu that pops up, type “%windir%inf”.
  4. Click OK.
  5. Find the inf information file and right-click it.
  6. Hit Rename and type in “Bth.bak”.

Method 2: Download the Driver

Find the exact model of your Bluetooth device by typing in your laptop model name in Google. Once you’ve found it, download the corresponding driver and install it.

Method 3: Install the Driver

The third, and perhaps the easiest way of reinstalling the Bluetooth Enumerator is to simply update it.

  1. Click Start.
  2. Type in “devmgmt.msc” and hit enter.
  3. Find your Bluetooth dongle.
  4. Right-click it.
  5. Click Update Driver.
  6. Follow all the steps in the Hardware Update Wizard.

Is the Microsoft Bluetooth Enumerator Useful?

Although we used to use the Bluetooth technology for transferring files, such as songs and photos, it is much easier to do this online nowadays. However, Bluetooth is vicariously omnipresent in our lives and we don’t even notice it. For one, we use it for wireless speakers to listen to our favorite music or talk on the phone. We use it for connecting to our car. And we will continue using it as the IoT (the Internet of Things) starts growing in the future.

Without the Microsoft Bluetooth Enumerator, your laptop wouldn’t be able to communicate with wireless devices. Even if both devices that you’re trying to connect are internet-ready, the Bluetooth connection is much stronger, owing to less interference running around. If you don’t need the Bluetooth Enumerator at the moment and it’s interfering with other devices, you don’t need to uninstall it, you can simply disable it.
