Microsoft Confirms KB2862330 Windows 7 Update Problems:
So let's get the story straight. KB2862330 from the moment it was released indicated it might need two reboots to be properly installed.
Microsoft stated that in the known issues section at the top of the security bulletin from the moment it was released.
The system will reboot, start again and rather than coming up, will just restart a second time. It's expected and not a bug.
There are a few folks seeing issues with this update and quite frankly I expect it. This is a lot of updates in the kernel section with impact to usb drivers. Where we have a ton of third party development. And not always the greatest third party development.
So let's not blow these statements out of proportion to the reality.
