And indeed the problem seemed to only occur when I had Ubuntu open for a few hours. And after that I had switched over from Cygwin to Ubuntu 18.04 running on WSL. What had changed on my Windows recently? I had installed the 1809 update for its WSL feature.
I then looked at the problem from a different angle: this problem was new. It did not lead to any suitable culprit and it was not clear why this service was going all hammer and tongs on the cores. Looking into this service turned out to be a dead end. In the end, I had to try the same with Process Explorer and leave its window open to catch the rogue service: WmiPrvSE.exe. Opening Task Manager to watch what process was causing this was a dead end because Task Manager window would freeze when restored. Investigationįrom the minimized Task Manager CPU graph I could see that all 8 logical CPU cores seem to have been engaged 100 percent by some process. That would keep the fans silent for a few hours before they would start all over again. The only brute force solution that worked was to restart Windows. This started to happen without a fail every day. After I kept it open for a few hours, its fan would start spinning noisily and never stop. A problem started to happen last week with my Dell notebook running Windows 10.
