I just bought a Samsung Series 5 notebook, with Windows 8, but I found it unreasonably slow to reboot and install updates.
Last night I waited for 1h30 for it to install 1 update and reboot, when I finally gave up and switched it off during reboot. Another thing that I noticed is that HD I/O is too high for a reboot - the HDD light doesn't turn off during the process, and the notebook gets really warm.
I tried to reboot it another day, without any updates to install, and after 4 hours it was still in the reboot screen. I had to do a hard reboot.
I found specially weird that even with a worse machine, Windows 7 would do both things (install updates AND reboot machine) faster.
Does anyone know a way to speed things up? Is there any configuration that I can make? Is this a Windows 8 bug?
