Hotfix: Installing and searching for updates is slow, CPU utilization is high

DOWNLOAD_thumb2We have a couple recent hotfixes for Windows that you’ll want to be aware of if you install Windows updates by using System Center 2012 Configuration Manager (ConfigMgr 2012 or ConfigMgr 2012 R2). The problems addressed with these hotfixes have the following symptoms:

- When you install Windows updates by using System Center Configuration Manager, the installation takes a long time to complete and Configuration Manager becomes overloaded.

- The Svchost.exe process consumes 100 percent of the CPU usage when you try to upgrade to Windows 10. 

You may also experience issues related to updates installed during a Configuration Manager Task Sequence.

For complete details as well as download and installation instructions, please see the following:

    Also valid if you install updates with ConfigMgr 2007

    Dumb question time: How's this overlap with the releases of Windows Update Agent, the monthly releases? For example, the October 2015:

    Includes several of the same files, albeit slightly older, that the referenced KB. Are the "special" files going to be rolled into the next Windows Update Agent, or will this stand alone as its own update? From a deployment perspective it doesn't make a huge
    difference, but it's just a curiosity; MS has been dropping Windows Update Agents at a crazy rate since the Windows 10 upgrade started, and the overlap of "what's being fixed for Windows 10 upgrades" and "what actually impacts the Enterprise" was getting fuzzy.

    In Windows 7, installing and searching for updates is slow and high CPU usage occurs. I've installed the update/hotfix KB3102810 released Dec-08-2015. But the problem is still happening. Searching for updates takes a hour. And the CPU usage goes from a
    baseline of 49%, spiking to 76%.
    Is there another update/hotfix out there to correct this problem?
