Sometime in the last week or so, something occurred that caused me to lose all tabs in my task manager. I use task manager a lot, so this is a major inconvenience. I tried a system restore to three months ago, when I know task manager was working normally, but this did not fix the problem. Maybe I'm missing something stupid, here. Is this Windows corruption, or did I somehow accidentally turn all the task manager tabs off? A screenshot is attached to show you what the problem looks like. I did not crop the image: that is a clean Alt + PrintScreen of task manager. That is all I see when I pull task manager up. Please excuse the dark coloring, that is normal (for me) as I work in a dark environment. Ideas? My Google-fu is weak on this problem.
