  • Windows 7 Service Pack 1 (SP1)

  • Windows Server 2008 R2 Service Pack 1 (SP1)

  • Windows 8

  • Windows Server 2012

When you try to run a shell script to create many environment variables, the script fails and you receive an error message that resembles the following:

Cannot Allocate Memory


Note This issue only occurs when the environment variable block size is over 64 kilobytes (KB).

Cause

This issue occurs because the string length that is specified for the RtlSetEnvironmentVar API is incorrect when the environment variable block size is over 64 KB.

Resolution

This hotfix is also available at Microsoft Update Catalog

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, 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
    1.22xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    LDR

  • 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.
