  • Did you recently install KB3159706? If so you need to manually apply the post-installation steps.


    Make sure to perform all of the steps, including the ones for SSL even if you don't have SSL Enabled.

    If not and those were already previously applied,Have a peek at my Adamj Clean-WSUS script. It is the last WSUS Script you will ever need.


    What it does:

    1. Remove all Drivers from the WSUS Database.
    2. Shrink your WSUSContent folder's size by declining superseded updates.
    3. Remove declined updates from the WSUS Database.
    4. Clean out all the synchronization logs that have built up over time (configurable, with the default keeping the last 14 days of logs).
    5. Compress Update Revisions.
    6. Remove Obsolete Updates.
    7. Computer Object Cleanup (configurable, with the default of deleting computer objects that have not synced within 30 days).
    8. Application Pool Memory Configuration to display the current private memory limit and easily increase it by any configurable amount.
    9. Run the Recommended SQL database Maintenance script on the actual SQL database.
    10. Run the Server Cleanup Wizard.

    It will email the report out to you or save it to a file, or both.

    Although the script is lengthy, it has been made to be super easy to setup and use. There are some prerequisites and instructions at the top of the script. After installing the prerequisites and configuring the variables for your environment, simply run:

    .\Clean-WSUS.ps1 -FirstRun

    and then

    .\Clean-WSUS.ps1 -InstallTask

    If you wish to view or increase the Application Pool Memory Configuration, you must run it with the required switch. See Get-Help .\Clean-WSUS.ps1 -Examples

    If you're having trouble, there's also a -HelpMe option that will create a log so you can send it to me for support.

  • Sorry, I did not mention.  The WSUS service is running on a Windows 2008 server.  I cannot use that KB.

  • Hi EdKC,

    1. Is it a newly installed WSUS server, please check if you select "Drivers" in classifications.

    2. Please check the version of the WSUS server, if its not .274, please upgrade the WSUS server:

    WSUS 3.0 (SP2): Build 3.2.7600.226
    WSUS 3.0 (SP2) + KB2720211: Build 3.2.7600.251
    WSUS 3.0 (SP2) + KB2734608: Build 3.2.7600.256
    WSUS 3.0 (SP2) + KB2828185: Build 3.2.7600.262
    WSUS 3.0 (SP2) + KB2938066: Build 3.2.7600.274

    3. Please check the WSUS event log in event viewer, check if there are errors, if yes, check the detailed information of the error.

    Best Regards,
