A user complained about his very slow computer. Couldn't find very much at first. When I looked at Task Manager processes, I noticed about 5 iterations of chrome.exe running. He claimed only a couple of tabs on chrome were open. I looked, and sure enough only a couple were running (that I could see. I closed them with end process in task manager. I opened one up again. Task manager now showed 12 iterations running. Huge amounts of memory were being consumed. What's going on?
