WMI Provider Host spikes CPU usage

The last couple of weeks my computer (running Windows 8.1) was working so hard steam came out of the exhaust. In the Task Manager I found WMI Provider Host was using about 25% of the CPU on my system.

On StackExchange the same question is answered. To find which services depend on WMI Provider Host: open Computer Management > Services > Windows Management Instrumentation and go to tab Dependencies.

Dell Data Vault causes problems

I’ve performed a Windows Clean Boot to find the service which was causing this. The spike takes place a couple of minutes after a reboot. In the end it turned out the Dell Data Vault / Dell Data Vault Wizard was the cause of this.

Afterwards I found Dell was aware of problems with these services, but running the Dell PC Checkup didn’t give any results…

Update (2015-07-30):
I just did a reinstall of Dell SupportAssist and this uninstalled the Dell Data Vault / Wizard programs. I couldn’t figure out what these programs are doing anyway. Dell Support said they collect data from .dll files, but not why this done.
