The following are a few examples of counters of such counter types that are affected by this change: 

  • \LogicalDisk\Avg. Disk sec/Write

  • \LogicalDisk\Avg. Disk sec/Read

  • \LogicalDisk\Avg. Disk sec/Transfer

  • \PhysicalDisk\Avg. Disk sec/Write

  • \PhysicalDisk\Avg. Disk sec/Read

  • \PhysicalDisk\Avg. Disk sec/Transfer

Windows 7 and Windows Server 2008 R2 file information notesImportant Windows 7 hotfixes and Windows Server 2008 R2 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 7/Windows Server 2008 R2" 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, SR_Level (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

    6.1.760 1.17xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    GDR

    6.1.760 1.22xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    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 for Windows 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
