I had a USB WiFi dongle installed and working great. Then someone pulled it out of my computer, without talking to me, so they could use it. I found another in the office...exact same model...plug it in. Drivers don't work. Can't update them. Reinstallation crashes. Try to restart computer, it crashes. Restart computer and now Outlook won't even open. No idea what to do now, but this is going on an hour and counting of no productivity.

WTF Windows? You can't even handle a WiFi dongle right?
