    System issues after latest Windows Updates for Windows 8

    I had problems installing the latest Windows updates. The Update Scan froze intermittently. So I only partially updated. I decided to do a system restore. And then started with the updates again. One at a time. Restarting after each one etc. Eventually I thought they were all installed successfully.

    However, this morning every time the laptop is idle, Windows Module Installer kicks in and really works the system and doesn't stop until i start using the laptop again. It's using 50% cpu ... and working my fan hard. This issue happened once before after a Windows Update .. couple of months ago[i believe there was one particular update causing the problem and I managed to remove it and didn't install it again.

    I've had a look at all the updates to make sure they were installed successfully. One stands out ...

    As the Update Scan Froze part way through ... aI had to do a system restore and start again.

    Update for Windows 8 for x64-based Systems (KB2871389) : FAILED

    I decided to uninstall the 'successfully' installed (KB2871389) as I wondered if it was the glitch causing my issues.

    These things may not be related to the issues I'm having. But I thought I'd mention them anyway.

    And advice would be welcome. Thanks.

    Try downloading and installing that KB2871389 manually:

    Update is available that prepares Windows 8 and Windows RT-based computers for the update to Windows 8.1 and Windows 8.1 RT

    Since the description indicates it is intended to prep your computer for 8.1, I can see where it could run for some time after the initial install. FYI, I have also noticed this behavior anytime Windows Update installs a .net framework update. Good luck.

    As I understand it, the Windows Module Installer is trying to compress setup files, to save space. This compression uses the CPU and disk quite hard.

    I found that if you just let it run for a while (maybe hours rather than minutes), it will eventually complete what it's trying to do and stop.

    There is a troubleshooter in Windows 8, it helped fix my similar issue: Troubleshooting problems with installing updates - Microsoft Windows Help

    Once it has run, and I think after a restart, the updates downloaded, and installed correctly.
