if Microsoft did it with Reduced update restarts. it might be better. we'll see, when windows 8 was released.
we needed restart Windows after installing windows updates, Because windows service (file system) and other programs still work and need to be stopped (restarted)
and, by the way, I restarted the laptop it did not matter to me. The important thing is; windows update is installed correctly.
That's a better step for Microsoft since there is no reason of so many restarts just to apply the effect of the updates and make the task more easier when updates were less restarts.
