Bing works fine here.
Yeah, I bet so. Still can't access Bing.com and just check it using Down for Everyone or Just Me, it says that it's just me.
No. It's not trouble with Windows Update after 6.0.1367. It's an intermittent problem of black blank screen when I log into Windows and sometimes an unusual high use of CPU (80-100%) after log in while the system is idle put my system down to a crawl. I'm simply kinda lazy to troubleshoot it, so I choose one that simply work for me. Though, I kind of feel a little bit unsafe without the Web and Network Shield protecting me at the time.
