ETD Control Center using 51% of cpu

Hi Francis,

Thank you for contacting Microsoft Community. I understand that ETD Control Center uses 51% CPU on your computer. I will surely help you with this.

ETD Control Center" belongs to "ELAN Smart-Pad" made by "ELAN Microelectronic Corp.". It enables the user the possibility to use multi-finger moves on the touch pad.

To understand the issue better, let me know what is the make and model of the laptop?

This issue could have occurred due to these reasons:
1. Outdated Touchpad driver or software.

2. Conflict between third party applications.

Try the steps listed here and check if it helps:

Method 1:
I would suggest you to download and install latest driver and software for touchpad from the computer manufacturer website and check if it helps.

Method 2:
If the issue persists, I would suggest you to boot the computer to Safe Mode and check if the issue occurs or not. If not, I would suggest you to set the computer in a clean boot state and check if it helps.

Step 1:
Boot the computer to Safe Mode. In Safe Mode computer starts with minimal set of drivers and files.

Step 2:
If the issue do not occur in Safe Mode perform a clean boot and check. Setting the system in a clean boot state will help to identify if any third party applications or startup items are causing the issue.
