Fix High CPU Usage from AVCTP on Windows 11: Step-by-Step Solutions

If you're a Windows 11 user and have been feeling the heat—not just from your computer's performance but from your CPU utilization skyrocketing due to AVCTP, fear not! You're not alone in this digital battlefield. Many users have reported a similar experience, particularly when engaging with Bluetooth multimedia devices, such as headphones or speakers.

What is AVCTP and Why Should You Care?​

AVCTP, or Audio/Video Control Transport Protocol, is part of the Bluetooth stack that manages the streaming of audio and video data between devices. When all's working smoothly, it acts like the invisible hand, deftly managing your multimedia interactions. However, when things go awry, AVCTP can take over your CPU resources, leading to sluggish performance and frustratingly unresponsive systems.

Users experiencing this issue may notice:

• Lagging System: Applications take longer to respond, sometimes even freezing altogether.
• Noise and Distortion: Strange audio artifacts may accompany the choppy performance, turning your favorite tunes into a poor-quality version.
• Resource Hog: Observing Task Manager may reveal AVCTP is consuming an unusual amount of CPU resources, often peaking above the usual range.

Here’s the good news: this issue can often be mitigated through a variety of methods. Let’s dive into some practical solutions:
