WmiPrvSE.exe causing lag spikes

So my brother has a pretty weird problem with laptop. This process:

Causes the CPU usage to raise to about 50% every few seconds, the graph in task manager looks like this while idle.

I’ve tried searching online for any clues, but after an hour I haven’t found anything. I’ve tried shutting down the process, but it restarts itself automatically immediately after and it’s not appearing on safe mode. I’m asking if you could help me with this, because I have no idea what to do about this.
And sorry for a bit misleading title.

Never mind, he fixed it somehow.
