I got a red dot on my taskbar, mouse over it and it says Updates, you need to restart the PC.
So I restarted and the red dot was still there, so I clicked on the red dot and got a screen with a RESTART in a box, I clicked on it and this time it went to the blue screen with the 'Updating Do not turn off the computer' message.

After a time it completed the updates, but why was my normal restart different than the one that did it from ticking on the box on the page MS threw up?
