Was just surfing the web a bit this morning on my i3 and suddenly the fan started blowing hard. Thinking this was odd I checked my Task Manager and was surprised to see the Windows Module Installer taking up 25% of my CPU. I then checked updates to see what was being "installed" in the background. Turns out nothing. So why is Windows Module Installer churning my CPU when nothing is being installed? Very odd. Went on for about 5 minutes then quit on its own. Checked in Services and Windows Installer was already set to "Manual" so it should not have been able to start on its own. Disabled automatic SSD optimization just in case that was the culprit. Will scan for viruses. Any ideas?
