Issue: How to fix Windows Audio Endpoint Builder high CPU usage?
Hello. I turned on my Windows PC today in the morning and found out that Windows Audio Endpoint Builder is taking up to 50% of my CPU. I tried disabling it, but then my computer is left without a sound, so this is not an option. I also tried to restart my PC several times, but it did not help, and the process keeps spiking. Any help, please?
Windows has plenty of processes to ensure that all its functions run as intended. This is why, if you would open the Task Managed, you would see dozens of entries, most of which lay doormat and do not consume any resources whatsoever. The process usage spikes whenever it is used – it is normal behavior and disappears as soon as the process is no longer in use.
