Symptoms

Consider the following scenario. You connect a USB flash drive to a computer that is running Windows 7 or Windows Server 2008 R2. You try to run one of the following Windows Management Instrumentation Command-line (WMIC) tool commands to query the hard disk drives on the computer:

wmic diskdrive get *

wmic diskdrive get serialNumberIn this scenario, you receive an error message that resembles the following:

Invalid XML content

Cause

This issue occurs because the XML parser treats the control characters that are included in the serial number of some drives as invalid. Therefore, the XML parser cannot parse content that includes these control characters. This behavior causes valid results for other drives to be displayed incorrectly, together with the behavior that is mentioned in the "Symptoms" section.

Windows 7 and Windows Server 2008 R2 file information notes


Important 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, 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

    6.1.760
    1.17xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    GDR

    6.1.760
    1.21xxx

    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 critical 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.
