Windows 8.x Tablet Running Hot

With a Surface Pro 3 I’m seeing TIWorker.exe running at around 35%-50% CPU.  This really pushes the device and it gets really hot and the fan kicks in.


Running the set of commands below helped but it is important to note that I ran the steps a few times across a couple of reboots.

Don’t be surprised if you see TIWorker.exe spiking a few hours later as the process is valid and is expected to run according to internal Windows scheduling.

Bottom line…  run the steps a few times before having an expectation of the fundamental being issues flushed out.
