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?

  • how much memory does it have?

    Try sfc /scanNow to see if there is any disk corruption.

  • Windows 8 on my my laptop with a normal HDD boots within a reasonable time (no slower than Windows 7); on my desktop with an SSD it boots in ~8 seconds. Sounds like a problem specific to your machine, rather than a wider Windows 8 issue. Jan 18 '13 at 10:27

    Is application startup also slow? To me this sounds like a hardware problem. I'd run sfc as suggested above, but also chkdsk and one or more benchmark utilities to see if your disk and computer performs as expected. Jan 18 '13 at 10:46

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.

  • -1 Windows does not have such a service. It is installed by some third party software, which I would rather uninstall if it caused such p0rblems.

    It's Samsung software, which comes pre-installed on his Samsung laptop. No need to downvote. Have updated my answer to match.

  • Still, I would rather uninstall it.

  • Agreed, but I haven't tried it to provide it as an answer. I know that disabling the service works. Care to remove the downvote?

    A quick check indicates that it is made by the scientology company Condusiv (formerly known as Executive, of NT5 defrag infame). I would definitely uninstall it.

As suggested by others, this would seem to be a hardware fault. We are dealing with slow Windows 7 startup/shutdown in an enterprise setting at the moment but even we are only dealing with 8 minutes.

If it were a few minutes delay, I'd suggest a network issue but given the extreme time, I would think that it is a Hard Disk fault.

  • Run the program RUN.exe and then write MSCONFIG and Enter.
  • In the program go to the Services and click Hide all Microsoft services, now stop some services that you don't need, like AMD, Google Update, Hamachi, utilities from the manufacturer, Skype Updater.
  • Go to Task Manager, go to Startup and disable the unnecessary apps, for example: µTorrent, apps from the manufacturer, Skype, Java
  • Go to CCleaner, click Tools and go to Startup and disable apps from Windows, unnecessary, IE – all, Context menu – all, Scheduled Tasks – all
  • Restart the PC. This is to boot Windows 8 Faster.

So, after doing some testing and doing what was suggested by the answers above, I also uninstalled the antivirus that shipped with my notebook (Norton Security), replacing with another software, and the issue seems to be gone. I will need to test what happens when new updates are installed, but for now it is rebooting properly and after disabling IntelliMemory service, it is also faster to shutdown and startup.

Thanks guys!


I removed Condusiv IntelliMemory from my new Samsung Notebook with Windows 8, which was very slow. Now it is so fast! Definetely solved my problem. I removed it by Control Panel of old interface.
