Symptoms

This issue occurs when you run Windows Management Instrumentation (WMI) queries in a third-party WMI provider in Windows 8 or Windows Server 2012. If the third-party WMI provider has any memory leaks, WMI queries may fail in the WMI provider.

Cause

This issue occurs because memory is not automatically reclaimed by the WMI service host, and a WMI provider that has memory leaks can eventually exhaust the memory available to that WMI service host.

Windows 8 and Windows Server 2012 file information and notes

Important Windows 8 hotfixes and Windows Server 2012 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8/Windows Server 2012" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.2.920 0.16xxx

    Windows 8 and Windows Server 2012

    RTM

    GDR

    6.2.920 0.20 xxx

    Windows 8 and Windows Server 2012

    RTM

    LDR

    6.2.920 0.21xxx

    Windows 8 and Windows Server 2012

    RTM

    LDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
