How can I set high priority for bluetooth process/service in Windows 10? In Windows 7 ralink have process which have default high, but here is not any process connected with BT, without that I have delay on my BT headset :(


"svchost.exe - k bthsvcs" is the exact process that you need to act on if you wish to ensure High CPU Priority especially for things like A2DP/AptX and ensuring low latency as well as high audio quality. This was the reason I had to find out, as Games where making my Bluetooth Headphones skip and drop quality despite absolutely fine signal.

I used the Free (Nag's a little however) program Process Lasso to automate setting the process to High Priority. Problem Solved for me :)

Please note some programs do not separate each Service and just show "svchost.exe"


In Command Prompt execute tasklist /svc /fi “imagename eq svchost.exe” to see the list of process IDs.

Find the 'bthserv' service and notice the PID. Then Press CTRL + SHIFT + ESC, select the corresponding PID and set it to high priority.

  • Thank you for the end to end solution. So far so good.

Checkout the details tab of task Manager.

  1. Press CTRL + SHIFT + ESC
  2. In the window that pops up, click details tab.
  3. Right click the service you want.
  4. Mouse over Set Priority.

    I'm not sure why this was downvoted. This answers the specific question that was bolded of "How can I set high priority for bluetooth process/service in Windows 10?" Maybe because it didn't solve a problem that wasn't described here? Feb 22 '16 at 13:07

    I'm guessing because it doesn't identify which process should be prioritized, so it does not in fact answer the specific question.

    The question is about a headset. Your answer is about a mouse.

  • @Praesagus: This answer is not about a mouse. It is, in fact, not about a specific service at all. Oct 23 '18 at 6:59
