How to speed up Windows 8 on Samsung laptop?

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?

One of my friends also has a Samsung Windows 8 laptop, and disabling the Samsung service "IntelliMemory" service solved all of his issues.

1. Run services.msc


2. Locate "IntelliMemory"


3. Right Click -> Properties


4. Startup Type -> Disabled


5. Click "Stop"


6. Click "OK"


7. Reboot

IntelliMemory is a product which is installed by default on Samsung Windows 8 laptops. Samsung pre-loads IntelliMemory on most of their Windows computers, and it's the first thing to remove from a machine with an SSD drive. It can speed up slower conventional spinning hard disks by caching lots of stuff to RAM (memory), but when you have an SSD this isn't helpful and it tends to hog all the RAM. It can be safely removed from a system using an SSD drive.
