Windows 7/8/10 rundll32.exe high CPU?

by on Mar.01, 2016, under Techie

High CPU load caused by the rundll32.exe file seen with any windows 7, 8, 8.1, and 10 upgrade or installation. The following items need to be disabled:

  • Control Panel->Administrative tools->Task Scheduler
  • Browse into Task Scheduler Library->Microsoft->Windows->Customer Experience Improvement Program
  • Disable (right-click) all 3 of the following items under here: Consolidator, KernelCeipTask, UsbCeip
  • Reboot

You shouldn’t see rundll32.exe chewing up so much CPU. On a windows 10 machine (upgraded from Windows 7) I worked on tonight this change made it so when launching and App you went from 20-60 seconds of delay to almost no delay at all.
