I was in the process of downloading updates to my copy of Win10, when I saw this article. I don't think I'm going to chance it. Thanks, ElReg!
Having a local WSUS server has meant that I don't get the updates until I say to. But, since explorer.exe died today, and refused to restart without a complete reboot, I figured I might as well update the OS while I'm rebooting the machine anyway. I hadn't heard anything bad (well, worse than usual for Win10) about SP1 (Anniversary Edition) yet, so I figured it should be ok. Seems I was wrong, guess I'll just leave the Windows Update service disabled for another month, until they can patch their patch .
