Why does Window 8.1 boot slowly after upgrading?

My laptop (ASUS N550JV) has a problem: Several months ago, I upgraded my laptop from Windows 8 to Windows 8.1. (using Microsoft’s store), but now Windows’ start-up is speed is very slow! (up to 5-10 minutes for each boot of Windows)

After Windows booted, I opened the Task Manager view and I realized that a file called “System” is in use by the HDD and it took up 100% of the CPU’s resources.

I tried to perform a Windows 8.1 Repair and I also attempted to Refresh Windows.

I have used this method:

http://windows.microsoft.com/en-us/windows-8/restore-refresh-reset-pc

That was met with this error for refresh:

“Some file are missing. Your windows installation or recovery media will provide these files.”

And this error for Repair (in SrtTrail.txt log file):

    Try process explorer
    http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
    In the taskbar select View and check 'Show Process Tree' and 'Show Lower
    Pane' option (DLL).click on the CPU column to sort processes by %CPU usage
    if you see green color that means a process is started deactivating that process can reduce cpu usage
    right click on system and choose properties
    If background process is Purple)– Process Explorer thinks that can be malware

    Your repair log suggest that you were trying to use the Windows 8.0 recovery and repair tools on your (broken) Windows 8.1 installation. Unfortunately the 8.1 upgrade tends to create a new recovery and repair partition without telling your system to actually use it.

    At this point I would ask whether you have a Windows 8.1 recovery or installation media on a USB stick or a DVD. Because if you don't there is no point trying to fix the above. You'd still be stuck with missing the files required to repair the installation.

    I suggest to backup all of your data either using the broken and slow Windows 8.1 installation or something like a Linux Live CD.
    Once you backed up all your data restart and press F9 during boot. That should present you either with the Window Setup [EMS] which should allow you to restore your system to factory defaults or the Windows Troubleshooting options where you can select to "reset your PC".

    * Unfortunately I couldn't find a clear answer as to which recovery options are available for your model and what they may require in terms of user created media.

    Worst case scenario you will need to get a hold of a Windows 8.0 OEM installation media from someone else or (try) the ASUS support. You can then perform a fresh installation on your system.

    In the future I strongly suggest looking into ASUS Backtracker or the Windows built-in recovery media options. Whichever is suited for your model.
    http://www.asus.com/support/FAQ/1008642/

    In a worst case scenario your hard drive actually fails and no recovery or restore option on it will be available to you. So if your device didn't come with recovery disks make sure to create them yourself.

    This is a fairly tough issue to diagnose because of the many factors that go into this kind of failure. The key point that I would point out is the failed system restore and the failed system refresh. A restore or refresh overwrite the old operating system files, which means if it's not working, it could be a hard drive that's at the very beginning stages of failure. As a hard drive ages, it loses the ability to write data reliably, meaning it still writes most data, but some data won't write properly, depending on what portion of the hard drive it inhabits. This sometimes causes the issues that you're seeing, including slow boots (which is common because Windows 8.1 refreshes/restores will require a large number of updates) and other problems.

    Given that your laptop worked fine up until the upgrade is troubling because this suggests that hardware is not bad and that it could be related to the upgrade itself. Also, Windows 8.1 upgrades have been known to cause problems.

    We've published articles on troubleshooting hard drive failures:

    http://www.makeuseof.com/tag/how-to-diagnose-and-fix-a-dead-hard-drive-to-recover-data/

    But in your case the first step I'd take is to use a livedisk to determine whether or not the hard drive is starting to fail. Asus has its own diagnostic tools:

    http://support.asus.com/Diagnosis/SelfDiagnostic.aspx?SLanguage=en

    The best tool is probably PartedMagic's LiveDisk/USB:

    http://www.makeuseof.com/tag/parted-magic-complete-hard-drive-toolbox-live-cd/

    There are also drive-specific software out there. However because I don't know the manufacturer of the hard drive, PartedMagic is probable the best tool. There are other options available, as well.

    If that doesn't work, it's probably related to the upgrade itself. There are other experts around here who can recommend a better means of trouble-shooting Windows 8.1 upgrade issues other than myself. They should supply a response soon.
