To prevent the action center or Windows search box from constantly popping open when the trackpad is touched, you could try any of the tips to fix the issue. It seems that the touchpad driver is not compatibility within the Windows 10 and has some bugs. So I had to click on the left key to open all the apps. After installed the Windows 10 anniversary update with up to date drivers, it caused the action center popping up, even sometimes I moved my mouse. I was able to push my touchpad to open any program in Windows 8.
A lot of users have reported the problem on their laptop such as Dell, HP Pavilion, HP Spectre x360 and others.
